Overview

A new worksheet is created by calling the add_worksheet() method from a workbook object:

worksheet1 = workbook.add_worksheet
worksheet2 = workbook.add_worksheet

The following methods are available through a new worksheet:

write
write_number
write_string
write_rich_string
write_blank
write_row
write_col
write_date_time
write_url
write_url_range
write_formula
write_comment
show_comments
set_comments_author
insert_image
insert_chart
insert_shape
data_validation
conditional_formatting
add_sparkline
add_table
name
activate
select
hide
set_first_sheet
protect
set_selection
set_row
set_column
outline_settings
freeze_panes
split_panes
merge_range
merge_range_type
set_zoom
right_to_left
hide_zero
set_tab_color
autofilter
filter_column
filter_column_list

Cell notation

WriteXLSX supports two forms of notation to designate the position of cells: Row-column notation and A1 notation.

Row-column notation uses a zero based index for both row and column while A1 notation uses the standard Excel alphanumeric sequence of column letter and 1-based row. For example:

(0, 0)      # The top left cell in row-column notation.
('A1')      # The top left cell in A1 notation.

(1999, 29)  # Row-column notation.
('AD2000')  # The same cell in A1 notation.

Row-column notation is useful if you are referring to cells programmatically:

(0..9).each do |i|
  worksheet.write(i, 0, 'Hello')    # Cells A1 to A10
end

A1 notation is useful for setting up a worksheet manually and for working with formulas:

worksheet.write('H1', 200)
worksheet.write('H2', '=H1+1')

In formulas and applicable methods you can also use the A:A column notation:

worksheet.write('A1', '=SUM(B:B)')

The Writexlsx::Utility module that is included in the distro contains helper functions for dealing with A1 notation, for example:

include Writexlsx::Utility

row, col = xl_cell_to_rowcol('C2')    # (1, 2)
str      = xl_rowcol_to_cell(1, 2)    # C2

For simplicity, the parameter lists for the worksheet method calls in the following sections are given in terms of row-column notation. In all cases it is also possible to use A1 notation.

PAGE SET-UP METHODS

Page set-up methods affect the way that a worksheet looks when it is printed. They control features such as page headers and footers and margins. These methods are really just standard worksheet methods. They are documented here in a separate section for the sake of clarity.

The following methods are available for page set-up:

set_landscape()
set_portrait()
set_page_view()
set_paper()
center_horizontally()
center_vertically()
set_margins()
set_header()
set_footer()
repeat_rows()
repeat_columns()
hide_gridlines()
print_row_col_headers()
print_area()
print_across()
fit_to_pages()
set_start_page()
set_print_scale()
set_h_pagebreaks()
set_v_pagebreaks()

A common requirement when working with WriteXLSX is to apply the same page set-up features to all of the worksheets in a workbook. To do this you can use the sheets() method of the workbook class to access the array of worksheets in a workbook:

workbook.sheets.each do |worksheet|
  worksheet.set_landscape
end

Instance Method Details

#activate ⇒ Object

Set this worksheet as the active worksheet, i.e. the worksheet that is displayed when the workbook is opened. Also set it as selected.

The activate() method is used to specify which worksheet is initially visible in a multi-sheet workbook:

worksheet1 = workbook.add_worksheet('To')
worksheet2 = workbook.add_worksheet('the')
worksheet3 = workbook.add_worksheet('wind')

worksheet3.activate

This is similar to the Excel VBA activate method. More than one worksheet can be selected via the select() method, see below, however only one worksheet can be active.

The default active worksheet is the first worksheet.

#add_sparkline(param) ⇒ Object

Add sparklines to the worksheet.

#add_table(*args) ⇒ Object

Add an Excel table to a worksheet.

The add_table() method is used to group a range of cells into an Excel Table.

worksheet.add_table('B3:F7', { ... } )

This method contains a lot of parameters and is described in detail in a separate section “TABLES IN EXCEL”.

#autofilter(*args) ⇒ Object

:call-seq:

autofilter(first_row, first_col, last_row, last_col)

Set the autofilter area in the worksheet.

This method allows an autofilter to be added to a worksheet. An autofilter is a way of adding drop down lists to the headers of a 2D range of worksheet data. This is turn allow users to filter the data based on simple criteria so that some data is shown and some is hidden.

To add an autofilter to a worksheet:

worksheet.autofilter(0, 0, 10, 3)
worksheet.autofilter('A1:D11')    # Same as above in A1 notation.

Filter conditions can be applied using the filter_column() or filter_column_list() method.

See the autofilter.rb program in the examples directory of the distro for a more detailed example.

#conditional_formatting(*args) ⇒ Object

:call-seq:

conditional_formatting(cell_or_cell_range, options)

This method handles the interface to Excel conditional formatting.

We allow the format to be called on one cell or a range of cells. The hashref contains the formatting parameters and must be the last param:

conditional_formatting(row, col, {...})
conditional_formatting(first_row, first_col, last_row, last_col, {...})

The conditional_format() method is used to add formatting to a cell or range of cells based on user defined criteria.

worksheet.conditional_formatting('A1:J10',
    {
        :type     => 'cell',
        :criteria => '>=',
        :value    => 50,
        :format   => format1
    }
)

This method contains a lot of parameters and is described in detail in a separate section “CONDITIONAL FORMATTING IN EXCEL”.

See also the conditional_format.rb program in the examples directory of the distro

#convert_date_time(date_time_string) ⇒ Object

convert_date_time(date_time_string)

The function takes a date and time in ISO8601 “yyyy-mm-ddThh:mm:ss.ss” format and converts it to a decimal number representing a valid Excel date.

Dates and times in Excel are represented by real numbers. The integer part of the number stores the number of days since the epoch and the fractional part stores the percentage of the day in seconds. The epoch can be either 1900 or 1904.

Parameter: Date and time string in one of the following formats:

yyyy-mm-ddThh:mm:ss.ss  # Standard
yyyy-mm-ddT             # Date only
          Thh:mm:ss.ss  # Time only

Returns:

A decimal number representing a valid Excel date, or
nil if the date is invalid.

#data_validation(*args) ⇒ Object

:call-seq:

data_validation(cell_or_cell_range, options)

Data validation is a feature of Excel which allows you to restrict the data that a users enters in a cell and to display help and warning messages. It also allows you to restrict input to values in a drop down list.

A typical use case might be to restrict data in a cell to integer values in a certain range, to provide a help message to indicate the required value and to issue a warning if the input data doesn’t meet the stated criteria. In WriteXLSX we could do that as follows:

worksheet.data_validation('B3',
    {
        :validate        => 'integer',
        :criteria        => 'between',
        :minimum         => 1,
        :maximum         => 100,
        :input_title     => 'Input an integer:',
        :input_message   => 'Between 1 and 100',
        :error_message   => 'Sorry, try again.'
    })

For more information on data validation see the following Microsoft support article “Description and examples of data validation in Excel”: support.microsoft.com/kb/211485.

The following sections describe how to use the data_validation() method and its various options.

The data_validation() method is used to construct an Excel data validation.

It can be applied to a single cell or a range of cells. You can pass 3 parameters such as (row, col, …) or 5 parameters such as (first_row, first_col, last_row, last_col, …). You can also use A1 style notation. For example:

worksheet.data_validation( 0, 0,       {...} )
worksheet.data_validation( 0, 0, 4, 1, {...} )

# Which are the same as:

worksheet.data_validation( 'A1',       {...} )
worksheet.data_validation( 'A1:B5',    {...} )

See also the note about “Cell notation” for more information.

The last parameter in data_validation() must be a hash ref containing the parameters that describe the type and style of the data validation. The allowable parameters are:

:validate
:criteria
:value | minimum | source
:maximum
:ignore_blank
:dropdown

:input_title
:input_message
:show_input

:error_title
:error_message
:error_type
:show_error

These parameters are explained in the following sections. Most of the parameters are optional, however, you will generally require the three main options validate, criteria and value.

worksheet.data_validation('B3',
    {
        :validate => 'integer',
        :criteria => '>',
        :value    => 100
    })

validate

This parameter is passed in a hash ref to data_validation().

The validate parameter is used to set the type of data that you wish to validate. It is always required and it has no default value. Allowable values are:

:any
:integer
:decimal
:list
:date
:time
:length
:custom

:any is used to specify that the type of data is unrestricted. This is the same as not applying a data validation. It is only provided for completeness and isn’t used very often in the context of WriteXLSX.

:integer restricts the cell to integer values. Excel refers to this as ‘whole number’.

:validate => 'integer',
:criteria => '>',
:value    => 100,

:decimal restricts the cell to decimal values.

:validate => 'decimal',
:criteria => '>',
:value    => 38.6,

:list restricts the cell to a set of user specified values. These can be passed in an array ref or as a cell range (named ranges aren’t currently supported):

:validate => 'list',
:value    => ['open', 'high', 'close'],
# Or like this:
:value    => 'B1:B3',

Excel requires that range references are only to cells on the same worksheet.

:date restricts the cell to date values. Dates in Excel are expressed as integer values but you can also pass an ISO860 style string as used in write_date_time(). See also “DATES AND TIME IN EXCEL” for more information about working with Excel’s dates.

:validate => 'date',
:criteria => '>',
:value    => 39653, # 24 July 2008
# Or like this:
:value    => '2008-07-24T',

:time restricts the cell to time values. Times in Excel are expressed as decimal values but you can also pass an ISO860 style string as used in write_date_time(). See also “DATES AND TIME IN EXCEL” for more information about working with Excel’s times.

:validate => 'time',
:criteria => '>',
:value    => 0.5, # Noon
# Or like this:
:value    => 'T12:00:00',

:length restricts the cell data based on an integer string length. Excel refers to this as ‘Text length’.

:validate => 'length',
:criteria => '>',
:value    => 10,

:custom restricts the cell based on an external Excel formula that returns a TRUE/FALSE value.

:validate => 'custom',
:value    => '=IF(A10>B10,TRUE,FALSE)',

criteria

This parameter is passed in a hash ref to data_validation().

The criteria parameter is used to set the criteria by which the data in the cell is validated. It is almost always required except for the list and custom validate options. It has no default value. Allowable values are:

'between'
'not between'
'equal to'                  |  '=='  |  '='
'not equal to'              |  '!='  |  '<>'
'greater than'              |  '>'
'less than'                 |  '<'
'greater than or equal to'  |  '>='
'less than or equal to'     |  '<='

You can either use Excel’s textual description strings, in the first column above, or the more common symbolic alternatives. The following are equivalent:

:validate => 'integer',
:criteria => 'greater than',
:value    => 100,

:validate => 'integer',
:criteria => '>',
:value    => 100,

The list and custom validate options don’t require a criteria. If you specify one it will be ignored.

:validate => 'list',
:value    => ['open', 'high', 'close'],

:validate => 'custom',
:value    => '=IF(A10>B10,TRUE,FALSE)',

value | minimum | source

This parameter is passed in a hash ref to data_validation().

The value parameter is used to set the limiting value to which the criteria is applied. It is always required and it has no default value. You can also use the synonyms minimum or source to make the validation a little clearer and closer to Excel’s description of the parameter:

# Use 'value'
:validate => 'integer',
:criteria => '>',
:value    => 100,

# Use 'minimum'
:validate => 'integer',
:criteria => 'between',
:minimum  => 1,
:maximum  => 100,

# Use 'source'
:validate => 'list',
:source   => '$B$1:$B$3',

maximum

This parameter is passed in a hash ref to data_validation().

The maximum parameter is used to set the upper limiting value when the criteria is either ‘between’ or ‘not between’:

:validate => 'integer',
:criteria => 'between',
:minimum  => 1,
:maximum  => 100,

ignore_blank

This parameter is passed in a hash ref to data_validation().

The ignore_blank parameter is used to toggle on and off the ‘Ignore blank’ option in the Excel data validation dialog. When the option is on the data validation is not applied to blank data in the cell. It is on by default.

:ignore_blank => 0,  # Turn the option off

This parameter is passed in a hash ref to data_validation().

The dropdown parameter is used to toggle on and off the ‘In-cell dropdown’ option in the Excel data validation dialog. When the option is on a dropdown list will be shown for list validations. It is on by default.

:dropdown => 0,      # Turn the option off

input_title

This parameter is passed in a hash ref to data_validation().

The input_title parameter is used to set the title of the input message that is displayed when a cell is entered. It has no default value and is only displayed if the input message is displayed. See the input_message parameter below.

:input_title   => 'This is the input title',

The maximum title length is 32 characters.

input_message

This parameter is passed in a hash ref to data_validation().

The input_message parameter is used to set the input message that is displayed when a cell is entered. It has no default value.

:validate      => 'integer',
:criteria      => 'between',
:minimum       => 1,
:maximum       => 100,
:input_title   => 'Enter the applied discount:',
:input_message => 'between 1 and 100',

The message can be split over several lines using newlines, “n” in double quoted strings.

input_message => "This is\na test.",

The maximum message length is 255 characters.

show_input

This parameter is passed in a hash ref to data_validation().

The show_input parameter is used to toggle on and off the ‘Show input message when cell is selected’ option in the Excel data validation dialog. When the option is off an input message is not displayed even if it has been set using input_message. It is on by default.

:show_input => 0,      # Turn the option off

error_title

This parameter is passed in a hash ref to data_validation().

The error_title parameter is used to set the title of the error message that is displayed when the data validation criteria is not met. The default error title is ‘Microsoft Excel’.

:error_title   => 'Input value is not valid',

The maximum title length is 32 characters.

error_message

This parameter is passed in a hash ref to data_validation().

The error_message parameter is used to set the error message that is displayed when a cell is entered. The default error message is “The value you entered is not valid.nA user has restricted values that can be entered into the cell.”.

:validate      => 'integer',
:criteria      => 'between',
:minimum       => 1,
:maximum       => 100,
:error_title   => 'Input value is not valid',
:error_message => 'It should be an integer between 1 and 100',

The message can be split over several lines using newlines, “n” in double quoted strings.

:input_message => "This is\na test.",

The maximum message length is 255 characters.

error_type

This parameter is passed in a hash ref to data_validation().

The error_type parameter is used to specify the type of error dialog that is displayed. There are 3 options:

'stop'
'warning'
'information'

The default is ‘stop’.

show_error

This parameter is passed in a hash ref to data_validation().

The show_error parameter is used to toggle on and off the ‘Show error alert after invalid data is entered’ option in the Excel data validation dialog. When the option is off an error message is not displayed even if it has been set using error_message. It is on by default.

:show_error => 0,      # Turn the option off

Data Validation Examples

Example 1. Limiting input to an integer greater than a fixed value.

worksheet.data_validation('A1',
    {
        :validate        => 'integer',
        :criteria        => '>',
        :value           => 0,
    });

Example 2. Limiting input to an integer greater than a fixed value where the value is referenced from a cell.

worksheet.data_validation('A2',
    {
        :validate        => 'integer',
        :criteria        => '>',
        :value           => '=E3',
    });

Example 3. Limiting input to a decimal in a fixed range.

worksheet.data_validation('A3',
    {
        :validate        => 'decimal',
        :criteria        => 'between',
        :minimum         => 0.1,
        :maximum         => 0.5,
    });

Example 4. Limiting input to a value in a dropdown list.

worksheet.data_validation('A4',
    {
        :validate        => 'list',
        :source          => ['open', 'high', 'close'],
    });

Example 5. Limiting input to a value in a dropdown list where the list is specified as a cell range.

worksheet.data_validation('A5',
    {
        :validate        => 'list',
        :source          => '=$E$4:$G$4',
    });

#filter_column(col, expression) ⇒ Object

Set the column filter criteria.

The filter_column method can be used to filter columns in a autofilter range based on simple conditions.

NOTE: It isn’t sufficient to just specify the filter condition. You must also hide any rows that don’t match the filter condition. Rows are hidden using the set_row() visible parameter. WriteXLSX cannot do this automatically since it isn’t part of the file format. See the autofilter.rb program in the examples directory of the distro for an example.

The conditions for the filter are specified using simple expressions:

worksheet.filter_column('A', 'x > 2000')
worksheet.filter_column('B', 'x > 2000 and x < 5000')

The column parameter can either be a zero indexed column number or a string column name.

The following operators are available:

Operator        Synonyms
   ==           =   eq  =~
   !=           <>  ne  !=
   >
   <
   >=
   <=

   and          &&
   or           ||

The operator synonyms are just syntactic sugar to make you more comfortable using the expressions. It is important to remember that the expressions will be interpreted by Excel and not by ruby.

An expression can comprise a single statement or two statements separated by the and and or operators. For example:

'x <  2000'
'x >  2000'
'x == 2000'
'x >  2000 and x <  5000'
'x == 2000 or  x == 5000'

Filtering of blank or non-blank data can be achieved by using a value of Blanks or NonBlanks in the expression:

'x == Blanks'
'x == NonBlanks'

Excel also allows some simple string matching operations:

'x =~ b*'   # begins with b
'x !~ b*'   # doesn't begin with b
'x =~ *b'   # ends with b
'x !~ *b'   # doesn't end with b
'x =~ *b*'  # contains b
'x !~ *b*'  # doesn't contains b

You can also use * to match any character or number and ? to match any single character or number. No other regular expression quantifier is supported by Excel’s filters. Excel’s regular expression characters can be escaped using ~.

The placeholder variable x in the above examples can be replaced by any simple string. The actual placeholder name is ignored internally so the following are all equivalent:

'x     < 2000'
'col   < 2000'
'Price < 2000'

Also, note that a filter condition can only be applied to a column in a range specified by the autofilter() Worksheet method.

See the autofilter.rb program in the examples directory of the distro for a more detailed example.

Note Spreadsheet::WriteExcel supports Top 10 style filters. These aren’t currently supported by WriteXLSX but may be added later.

#filter_column_list(col, *tokens) ⇒ Object

Set the column filter criteria in Excel 2007 list style.

Prior to Excel 2007 it was only possible to have either 1 or 2 filter conditions such as the ones shown above in the filter_column method.

Excel 2007 introduced a new list style filter where it is possible to specify 1 or more ‘or’ style criteria. For example if your column contained data for the first six months the initial data would be displayed as all selected as shown on the left. Then if you selected ‘March’, ‘April’ and ‘May’ they would be displayed as shown on the right.

No criteria selected      Some criteria selected.

[/] (Select all)          [X] (Select all)
[/] January               [ ] January
[/] February              [ ] February
[/] March                 [/] March
[/] April                 [/] April
[/] May                   [/] May
[/] June                  [ ] June

The filter_column_list() method can be used to represent these types of filters:

worksheet.filter_column_list('A', 'March', 'April', 'May')

The column parameter can either be a zero indexed column number or a string column name.

One or more criteria can be selected:

worksheet.filter_column_list(0, 'March')
worksheet.filter_column_list(1, 100, 110, 120, 130)

NOTE: It isn’t sufficient to just specify the filter condition. You must also hide any rows that don’t match the filter condition. Rows are hidden using the set_row() visible parameter. WriteXLSX cannot do this automatically since it isn’t part of the file format. See the autofilter.rb program in the examples directory of the distro for an example. e conditions for the filter are specified using simple expressions:

#fit_to_pages(width = 1, height = 1) ⇒ Object

The fit_to_pages() method is used to fit the printed area to a specific number of pages both vertically and horizontally. If the printed area exceeds the specified number of pages it will be scaled down to fit. This guarantees that the printed area will always appear on the specified number of pages even if the page size or margins change.

worksheet1.fit_to_pages(1, 1)    # Fit to 1x1 pages
worksheet2.fit_to_pages(2, 1)    # Fit to 2x1 pages
worksheet3.fit_to_pages(1, 2)    # Fit to 1x2 pages

The print area can be defined using the print_area() method as described above.

A common requirement is to fit the printed output to n pages wide but have the height be as long as necessary. To achieve this set the height to zero:

worksheet1.fit_to_pages(1, 0)    # 1 page wide and as long as necessary

Note that although it is valid to use both fit_to_pages() and set_print_scale() on the same worksheet only one of these options can be active at a time. The last method call made will set the active option.

Note that fit_to_pages() will override any manual page breaks that are defined in the worksheet.

#freeze_panes(*args) ⇒ Object

:call-seq:

freeze_panes(row, col [ , top_row, left_col ] )

This method can be used to divide a worksheet into horizontal or vertical regions known as panes and to also “freeze” these panes so that the splitter bars are not visible. This is the same as the Window->Freeze Panes menu command in Excel

The parameters row and col are used to specify the location of the split. It should be noted that the split is specified at the top or left of a cell and that the method uses zero based indexing. Therefore to freeze the first row of a worksheet it is necessary to specify the split at row 2 (which is 1 as the zero-based index). This might lead you to think that you are using a 1 based index but this is not the case.

You can set one of the row and col parameters as zero if you do not want either a vertical or horizontal split.

Examples:

worksheet.freeze_panes(1, 0)    # Freeze the first row
worksheet.freeze_panes('A2')    # Same using A1 notation
worksheet.freeze_panes(0, 1)    # Freeze the first column
worksheet.freeze_panes('B1')    # Same using A1 notation
worksheet.freeze_panes(1, 2)    # Freeze first row and first 2 columns
worksheet.freeze_panes('C2')    # Same using A1 notation

The parameters top_row and left_col are optional. They are used to specify the top-most or left-most visible row or column in the scrolling region of the panes. For example to freeze the first row and to have the scrolling region begin at row twenty:

worksheet.freeze_panes(1, 0, 20, 0)

You cannot use A1 notation for the top_row and left_col parameters.

See also the panes.rb program in the examples directory of the distribution.

#hide ⇒ Object

Hide this worksheet.

The hide() method is used to hide a worksheet:

worksheet2.hide

You may wish to hide a worksheet in order to avoid confusing a user with intermediate data or calculations.

A hidden worksheet can not be activated or selected so this method is mutually exclusive with the activate() and select() methods. In addition, since the first worksheet will default to being the active worksheet, you cannot hide the first worksheet without activating another sheet:

worksheet2.activate
worksheet1.hide

#hide_gridlines(option = 1) ⇒ Object

Set the option to hide gridlines on the screen and the printed page.

This was mainly useful for Excel 5 where printed gridlines were on by default.

This method is used to hide the gridlines on the screen and printed page. Gridlines are the lines that divide the cells on a worksheet. Screen and printed gridlines are turned on by default in an Excel worksheet. If you have defined your own cell borders you may wish to hide the default gridlines.

worksheet.hide_gridlines

The following values of option are valid:

0 : Don't hide gridlines
1 : Hide printed gridlines only
2 : Hide screen and printed gridlines

If you don’t supply an argument or use nil the default option is true, i.e. only the printed gridlines are hidden.

#insert_chart(*args) ⇒ Object

:call-seq:

insert_chart(row, column, chart [ , x, y, scale_x, scale_y ] )

Insert a chart into a worksheet. The chart argument should be a Chart object or else it is assumed to be a filename of an external binary file. The latter is for backwards compatibility.

This method can be used to insert a Chart object into a worksheet. The Chart must be created by the add_chart() Workbook method and it must have the embedded option set.

chart = workbook.add_chart(:type => 'line', :embedded => 1)

# Configure the chart.
...

# Insert the chart into the a worksheet.
worksheet.insert_chart('E2', chart)

See add_chart() for details on how to create the Chart object and Writexlsx::Chart for details on how to configure it. See also the chart_*.rb programs in the examples directory of the distro.

The x, y, scale_x and scale_y parameters are optional.

The parameters x and y can be used to specify an offset from the top left hand corner of the cell specified by row and column. The offset values are in pixels.

worksheet1.insert_chart('E2', chart, 3, 3)

The parameters scale_x and scale_y can be used to scale the inserted image horizontally and vertically:

# Scale the width by 120% and the height by 150%
worksheet.insert_chart('E2', chart, 0, 0, 1.2, 1.5)

#insert_image(*args) ⇒ Object

:call-seq:

insert_image(row, column, filename [ , x, y, scale_x, scale_y ] )

Partially supported. Currently only works for 96 dpi images. This will be fixed in an upcoming release. – This method can be used to insert a image into a worksheet. The image can be in PNG, JPEG or BMP format. The x, y, scale_x and scale_y parameters are optional.

worksheet1.insert_image('A1', 'ruby.bmp')
worksheet2.insert_image('A1', '../images/ruby.bmp')
worksheet3.insert_image('A1', '.c:\images\ruby.bmp')

The parameters x and y can be used to specify an offset from the top left hand corner of the cell specified by row and column. The offset values are in pixels.

worksheet1.insert_image('A1', 'ruby.bmp', 32, 10)

The offsets can be greater than the width or height of the underlying cell. This can be occasionally useful if you wish to align two or more images relative to the same cell.

The parameters scale_x and scale_y can be used to scale the inserted image horizontally and vertically:

# Scale the inserted image: width x 2.0, height x 0.8
worksheet.insert_image('A1', 'perl.bmp', 0, 0, 2, 0.8)

See also the images.rb program in the examples directory of the distro.

Note: you must call set_row() or set_column() before insert_image() if you wish to change the default dimensions of any of the rows or columns that the image occupies. The height of a row can also change if you use a font that is larger than the default. This in turn will affect the scaling of your image. To avoid this you should explicitly set the height of the row using set_row() if it contains a font size that will change the row height.

BMP images must be 24 bit, true colour, bitmaps. In general it is best to avoid BMP images since they aren’t compressed. ++

#insert_shape(*args) ⇒ Object

Insert a shape into the worksheet.

This method can be used to insert a Shape object into a worksheet. The Shape must be created by the add_shape() Workbook method.

shape = workbook.add_shape(:name => 'My Shape', :type => 'plus')

# Configure the shape.
shape.set_text('foo')
...

# Insert the shape into the a worksheet.
worksheet.insert_shape('E2', shape)

See add_shape() for details on how to create the Shape object and Excel::Writer::XLSX::Shape for details on how to configure it.

The x, y, scale_x and scale_y parameters are optional.

The parameters x and y can be used to specify an offset from the top left hand corner of the cell specified by row and col. The offset values are in pixels.

worksheet1.insert_shape('E2', chart, 3, 3)

The parameters scale_x and scale_y can be used to scale the inserted shape horizontally and vertically:

# Scale the width by 120% and the height by 150%
worksheet.insert_shape('E2', shape, 0, 0, 1.2, 1.5)

Set all the page margins to the same value in inches.

There are several methods available for setting the worksheet margins on the printed page:

margins=()                # Set all margins to the same value
margins_left_right=()     # Set left and right margins to the same value
margins_top_bottom=()     # Set top and bottom margins to the same value
margin_left=()            # Set left margin
margin_right=()           # Set right margin
margin_top=()             # Set top margin
margin_bottom=()          # Set bottom margin

All of these methods take a distance in inches as a parameter. Note: 1 inch = 25.4mm. ;-) The default left and right margin is 0.7 inch. The default top and bottom margin is 0.75 inch. Note, these defaults are different from the defaults used in the binary file format by writeexcel gem.

#name ⇒ Object

The name() method is used to retrieve the name of a worksheet. For example:

workbook.sheets.each do |sheet|
  print sheet.name
end

For reasons related to the design of WriteXLSX and to the internals of Excel there is no set_name() method. The only way to set the worksheet name is via the add_worksheet() method.

#outline_settings(visible = 1, symbols_below = 1, symbols_right = 1, auto_style = 0) ⇒ Object

The outline_settings() method is used to control the appearance of outlines in Excel. Outlines are described in “OUTLINES AND GROUPING IN EXCEL”.

The visible parameter is used to control whether or not outlines are visible. Setting this parameter to 0 will cause all outlines on the worksheet to be hidden. They can be unhidden in Excel by means of the “Show Outline Symbols” command button. The default setting is 1 for visible outlines.

worksheet.outline_settings(0)

The symbols_below parameter is used to control whether the row outline symbol will appear above or below the outline level bar. The default setting is 1 for symbols to appear below the outline level bar.

The symbols_right parameter is used to control whether the column outline symbol will appear to the left or the right of the outline level bar. The default setting is 1 for symbols to appear to the right of the outline level bar.

The auto_style parameter is used to control whether the automatic outline generator in Excel uses automatic styles when creating an outline. This has no effect on a file generated by WriteXLSX but it does have an effect on how the worksheet behaves after it is created. The default setting is 0 for “Automatic Styles” to be turned off.

The default settings for all of these parameters correspond to Excel’s default parameters.

The worksheet parameters controlled by outline_settings() are rarely used.

Note, it is likely that not all of these paper types will be available to the end user since it will depend on the paper formats that the user’s printer supports. Therefore, it is best to stick to standard paper types.

worksheet.set_paper(1)    # US Letter
worksheet.set_paper(9)    # A4

If you do not specify a paper type the worksheet will print using the printer’s default paper.

#position_object_pixels(col_start, row_start, x1, y1, width, height, is_drawing = false) ⇒ Object

Calculate the vertices that define the position of a graphical object within the worksheet in pixels.

|     |            |     (x2,y2)|
+---- +------------+------------+

Example of an object that covers some of the area from cell A1 to cell B2.

Based on the width and height of the object we need to calculate 8 vars:

col_start, row_start, col_end, row_end, x1, y1, x2, y2.

We also calculate the absolute x and y position of the top left vertex of the object. This is required for images.

x_abs, y_abs

The width and height of the cells that the object occupies can be variable and have to be taken into account.

The values of col_start and row_start are passed in from the calling function. The values of col_end and row_end are calculated by subtracting the width and height of the object from the width and height of the underlying cells.

col_start    # Col containing upper left corner of object.
x1           # Distance to left side of object.
row_start    # Row containing top left corner of object.
y1           # Distance to top of object.
col_end      # Col containing lower right corner of object.
x2           # Distance to right side of object.
row_end      # Row containing bottom right corner of object.
y2           # Distance to bottom of object.
width        # Width of object frame.
height       # Height of object frame.

#print_across(across = true) ⇒ Object

Set the order in which pages are printed.

The print_across method is used to change the default print direction. This is referred to by Excel as the sheet “page order”.

worksheet.print_across

The default page order is shown below for a worksheet that extends over 4 pages. The order is called “down then across”:

[1] [3]
[2] [4]

However, by using the print_across method the print order will be changed to “across then down”:

[1] [2]
[3] [4]

|   |   A   |   B   |   C   |   D   |  ...
 ------------------------------------------
| 1 |       |       |       |       |  ...
| 2 |       |       |       |       |  ...
| 3 |       |       |       |       |  ...
| 4 |       |       |       |       |  ...
|...|  ...  |  ...  |  ...  |  ...  |  ...

The headers are the letters and numbers at the top and the left of the worksheet. Since these headers serve mainly as a indication of position on the worksheet they generally do not appear on the printed page. If you wish to have them printed you can use the print_row_col_headers() method :

worksheet.print_row_col_headers

Do not confuse these headers with page headers as described in the set_header() section above.

  end
end

#print_scale=(scale = 100) ⇒ Object

Set the scale factor of the printed page. Scale factors in the range 10 <= scale <= 400 are valid:

worksheet1.print_scale =  50
worksheet2.print_scale =  75
worksheet3.print_scale = 300
worksheet4.print_scale = 400

The default scale factor is 100. Note, print_scale=() does not affect the scale of the visible page in Excel. For that you should use set_zoom().

Note also that although it is valid to use both fit_to_pages() and print_scale=() on the same worksheet only one of these options can be active at a time. The last method call made will set the active option.

  scale_val = scale.to_i
  # Confine the scale to Excel's range
  scale_val = 100 if scale_val < 10 || scale_val > 400

  # Turn off "fit to page" option.
  @print_style.fit_page = false

  @print_style.scale              = scale_val
  @print_style.page_setup_changed = true
end

#protect(password = nil, options = {}) ⇒ Object

Set the worksheet protection flags to prevent modification of worksheet objects.

The protect() method is used to protect a worksheet from modification:

worksheet.protect

The protect() method also has the effect of enabling a cell’s locked and hidden properties if they have been set. A locked cell cannot be edited and this property is on by default for all cells. A hidden cell will display the results of a formula but not the formula itself.

See the protection.rb program in the examples directory of the distro for an illustrative example and the set_locked and set_hidden format methods in “CELL FORMATTING”.

You can optionally add a password to the worksheet protection:

worksheet.protect('drowssap')

Passing the empty string ” is the same as turning on protection without a password.

Note, the worksheet level password in Excel provides very weak protection. It does not encrypt your data and is very easy to deactivate. Full workbook encryption is not supported by WriteXLSX since it requires a completely different file format and would take several man months to implement.

You can specify which worksheet elements that you which to protect by passing a hash_ref with any or all of the following keys:

# Default shown.
options = {
    :objects               => false,
    :scenarios             => false,
    :format_cells          => false,
    :format_columns        => false,
    :format_rows           => false,
    :insert_columns        => false,
    :insert_rows           => false,
    :insert_hyperlinks     => false,
    :delete_columns        => false,
    :delete_rows           => false,
    :select_locked_cells   => true,
    :sort                  => false,
    :autofilter            => false,
    :pivot_tables          => false,
    :select_unlocked_cells => true
}

The default boolean values are shown above. Individual elements can be protected as follows:

worksheet.protect('drowssap', { :insert_rows => true } )

#repeat_columns(*args) ⇒ Object

:call-seq:

repeat_columns(first_col, last_col = nil)

Set the columns to repeat at the left hand side of each printed page.

For large Excel documents it is often desirable to have the first column or columns of the worksheet print out at the left hand side of each page. This can be achieved by using the repeat_columns() method. The parameters first_column and last_column are zero based. The last_column parameter is optional if you only wish to specify one column. You can also specify the columns using A1 column notation, see the note about “Cell notation”.

worksheet1.repeat_columns(0)        # Repeat the first column
worksheet2.repeat_columns(0, 1)     # Repeat the first two columns
worksheet3.repeat_columns('A:A')    # Repeat the first column

#repeat_formula(*args) ⇒ Object

:call-seq:

repeat_formula(row, column, formula [ , format ] )

Deprecated. This is a writeexcel gem’s method that is no longer required by WriteXLSX.

In writeexcel it was computationally expensive to write formulas since they were parsed by a recursive descent parser. The store_formula() and repeat_formula() methods were used as a way of avoiding the overhead of repeated formulas by reusing a pre-parsed formula.

In WriteXLSX this is no longer necessary since it is just as quick to write a formula as it is to write a string or a number.

The methods remain for backward compatibility but new WriteXLSX programs shouldn’t use them.

#repeat_rows(row_min, row_max = nil) ⇒ Object

Set the number of rows to repeat at the top of each printed page.

For large Excel documents it is often desirable to have the first row or rows of the worksheet print out at the top of each page. This can be achieved by using the repeat_rows() method. The parameters first_row and last_row are zero based. The last_row parameter is optional if you only wish to specify one row:

worksheet1.repeat_rows(0)    # Repeat the first row
worksheet2.repeat_rows(0, 1) # Repeat the first two rows

end

#right_to_left(flag = true) ⇒ Object

Display the worksheet right to left for some eastern versions of Excel.

The right_to_left() method is used to change the default direction of the worksheet from left-to-right, with the A1 cell in the top left, to right-to-left, with the he A1 cell in the top right.

worksheet.right_to_left

This is useful when creating Arabic, Hebrew or other near or far eastern worksheets that use right-to-left as the default direction.

# File 'lib/write_xlsx/worksheet.rb', line 1581

def right_to_left(flag = true)
  @right_to_left = !!flag
end

#select ⇒ Object

Set this worksheet as a selected worksheet, i.e. the worksheet has its tab highlighted.

The select() method is used to indicate that a worksheet is selected in a multi-sheet workbook:

worksheet1.activate
worksheet2.select
worksheet3.select

A selected worksheet has its tab highlighted. Selecting worksheets is a way of grouping them together so that, for example, several worksheets could be printed in one go. A worksheet that has been activated via the activate() method will also appear as selected.

  @selected = true
end

#set_column(*args) ⇒ Object

:call-seq:

set_column(firstcol, lastcol, width, format, hidden, level)

This method can be used to change the default properties of a single column or a range of columns. All parameters apart from first_col and last_col are optional.

If set_column() is applied to a single column the value of first_col and last_col should be the same. In the case where last_col is zero it is set to the same value as first_col.

It is also possible, and generally clearer, to specify a column range using the form of A1 notation used for columns. See the note about “Cell notation”.

Examples:

worksheet.set_column(0, 0, 20)    # Column  A   width set to 20
worksheet.set_column(1, 3, 30)    # Columns B-D width set to 30
worksheet.set_column('E:E', 20)   # Column  E   width set to 20
worksheet.set_column('F:H', 30)   # Columns F-H width set to 30

The width corresponds to the column width value that is specified in Excel. It is approximately equal to the length of a string in the default font of Arial 10. Unfortunately, there is no way to specify “AutoFit” for a column in the Excel file format. This feature is only available at runtime from within Excel.

As usual the format parameter is optional, for additional information, see “CELL FORMATTING”. If you wish to set the format without changing the width you can pass nil as the width parameter:

worksheet.set_column(0, 0, nil, format)

The format parameter will be applied to any cells in the column that don’t have a format. For example

worksheet.set_column( 'A:A', nil, format1 )    # Set format for col 1
worksheet.write( 'A1', 'Hello' )                  # Defaults to format1
worksheet.write( 'A2', 'Hello', format2 )        # Keeps format2

If you wish to define a column format in this way you should call the method before any calls to write(). If you call it afterwards it won’t have any effect.

A default row format takes precedence over a default column format

worksheet.set_row( 0, nil, format1 )           # Set format for row 1
worksheet.set_column( 'A:A', nil, format2 )    # Set format for col 1
worksheet.write( 'A1', 'Hello' )               # Defaults to format1
worksheet.write( 'A2', 'Hello' )               # Defaults to format2

The hidden parameter should be set to 1 if you wish to hide a column. This can be used, for example, to hide intermediary steps in a complicated calculation:

worksheet.set_column( 'D:D', 20,  format, 1 )
worksheet.set_column( 'E:E', nil, nil,    1 )

The level parameter is used to set the outline level of the column. Outlines are described in “OUTLINES AND GROUPING IN EXCEL”. Adjacent columns with the same outline level are grouped together into a single outline.

The following example sets an outline level of 1 for columns B to G:

worksheet.set_column( 'B:G', nil, nil, 0, 1 )

The hidden parameter can also be used to hide collapsed outlined columns when used in conjunction with the level parameter.

worksheet.set_column( 'B:G', nil, nil, 1, 1 )

For collapsed outlines you should also indicate which row has the collapsed + symbol using the optional collapsed parameter.

worksheet.set_column( 'H:H', nil, nil, 0, 0, 1 )

For a more complete example see the outline.rb and outline_collapsed.rb programs in the examples directory of the distro.

Excel allows up to 7 outline levels. Therefore the level parameter should be in the range 0 <= level <= 7.

#set_comments_author(author = '') ⇒ Object

Set the default author of the cell comments.

This method is used to set the default author of all cell comments.

worksheet.set_comments_author('Ruby')

Individual comment authors can be set using the author parameter of the write_comment method.

The default comment author is an empty string, ”, if no author is specified.

#set_first_sheet ⇒ Object

Set this worksheet as the first visible sheet. This is necessary when there are a large number of worksheets and the activated worksheet is not visible on the screen.

The activate() method determines which worksheet is initially selected. However, if there are a large number of worksheets the selected worksheet may not appear on the screen. To avoid this you can select which is the leftmost visible worksheet using set_first_sheet():

20.times { workbook.add_worksheet }

worksheet21 = workbook.add_worksheet
worksheet22 = workbook.add_worksheet

worksheet21.set_first_sheet
worksheet22.activate

This method is not required very often. The default value is the first worksheet.

#set_h_pagebreaks(*args) ⇒ Object

Store the horizontal page breaks on a worksheet.

Add horizontal page breaks to a worksheet. A page break causes all the data that follows it to be printed on the next page. Horizontal page breaks act between rows. To create a page break between rows 20 and 21 you must specify the break at row 21. However in zero index notation this is actually row 20. So you can pretend for a small while that you are using 1 index notation:

worksheet1.set_h_pagebreaks( 20 )    # Break between row 20 and 21

The set_h_pagebreaks() method will accept a list of page breaks and you can call it more than once:

worksheet2.set_h_pagebreaks( 20,  40,  60,  80,  100 )    # Add breaks
worksheet2.set_h_pagebreaks( 120, 140, 160, 180, 200 )    # Add some more

Note: If you specify the “fit to page” option via the fit_to_pages() method it will override all manual page breaks.

There is a silent limitation of about 1000 horizontal page breaks per worksheet in line with an Excel internal limitation.

#set_header(string = '', margin = 0.3) ⇒ Object

Set the page header caption and optional margin.

Headers and footers are generated using a string which is a combination of plain text and control characters. The margin parameter is optional.

The available control character are:

Control             Category            Description

Text in headers and footers can be justified (aligned) to the left, center and right by prefixing the text with the control characters &L, &C and &R.

For example (with ASCII art representation of the results):

worksheet.set_header('&LHello')

For simple text, if you do not specify any justification the text will be centred. However, you must prefix the text with &C if you specify a font name or any other formatting:

worksheet.set_header('Hello')

 ---------------------------------------------------------------
|                                                               |
|                          Hello                                |
|                                                               |

You can have text in each of the justification regions:

worksheet.set_header('&LCiao&CBello&RCielo')

 ---------------------------------------------------------------
|                                                               |
| Ciao                     Bello                          Cielo |
|                                                               |

The information control characters act as variables that Excel will update as the workbook or worksheet changes. Times and dates are in the users default format:

worksheet.set_header('&CPage &P of &N')

 ---------------------------------------------------------------
|                                                               |
|                        Page 1 of 6                            |
|                                                               |

worksheet.set_header('&CUpdated at &T')

 ---------------------------------------------------------------
|                                                               |
|                    Updated at 12:30 PM                        |
|                                                               |

You can specify the font size of a section of the text by prefixing it with the control character &n where n is the font size:

worksheet1.set_header('&C&30Hello Big' )
worksheet2.set_header('&C&10Hello Small' )

You can specify the font of a section of the text by prefixing it with the control sequence &“font,style” where fontname is a font name such as “Courier New” or “Times New Roman” and style is one of the standard Windows font descriptions: “Regular”, “Italic”, “Bold” or “Bold Italic”:

worksheet1.set_header('&C&"Courier New,Italic"Hello')
worksheet2.set_header('&C&"Courier New,Bold Italic"Hello')
worksheet3.set_header('&C&"Times New Roman,Regular"Hello')

It is possible to combine all of these features together to create sophisticated headers and footers. As an aid to setting up complicated headers and footers you can record a page set-up as a macro in Excel and look at the format strings that VBA produces. Remember however that VBA uses two double quotes “” to indicate a single double quote. For the last example above the equivalent VBA code looks like this:

.LeftHeader   = ""
.CenterHeader = "&""Times New Roman,Regular""Hello"
.RightHeader  = ""

To include a single literal ampersand & in a header or footer you should use a double ampersand &&:

worksheet1.set_header('&CCuriouser && Curiouser - Attorneys at Law')

As stated above the margin parameter is optional. As with the other margins the value should be in inches. The default header and footer margin is 0.3 inch. Note, the default margin is different from the default used in the binary file format by Spreadsheet::WriteExcel. The header and footer margin size can be set as follows:

worksheet.set_header('&CHello', 0.75)

The header and footer margins are independent of the top and bottom margins.

Note, the header or footer string must be less than 255 characters. Strings longer than this will not be written and a warning will be generated.

See, also the headers.rb program in the examples directory of the distribution.

set_margin_* methods are deprecated. use margin_*=().

Set all the page margins to the same value in inches.

There are several methods available for setting the worksheet margins on the printed page:

set_margins()        # Set all margins to the same value
set_margins_LR()     # Set left and right margins to the same value
set_margins_TB()     # Set top and bottom margins to the same value
set_margin_left()    # Set left margin
set_margin_right()   # Set right margin
set_margin_top()     # Set top margin
set_margin_bottom()  # Set bottom margin

All of these methods take a distance in inches as a parameter. Note: 1 inch = 25.4mm. ;-) The default left and right margin is 0.7 inch. The default top and bottom margin is 0.75 inch. Note, these defaults are different from the defaults used in the binary file format by writeexcel gem.

#set_row(*args) ⇒ Object

:call-seq:

set_row(row [ , height, format, hidden, level, collapsed ] )

This method can be used to change the default properties of a row. All parameters apart from row are optional.

The most common use for this method is to change the height of a row:

worksheet.set_row(0, 20)    # Row 1 height set to 20

If you wish to set the format without changing the height you can pass nil as the height parameter:

worksheet.set_row(0, nil, format)

The format parameter will be applied to any cells in the row that don’t have a format. For example

worksheet.set_row(0, nil, format1)      # Set the format for row 1
worksheet.write('A1', 'Hello')          # Defaults to format1
worksheet.write('B1', 'Hello', format2) # Keeps format2

If you wish to define a row format in this way you should call the method before any calls to write(). Calling it afterwards will overwrite any format that was previously specified.

The hidden parameter should be set to 1 if you wish to hide a row. This can be used, for example, to hide intermediary steps in a complicated calculation:

worksheet.set_row(0, 20,  format, 1)
worksheet.set_row(1, nil, nil,    1)

The level parameter is used to set the outline level of the row. Outlines are described in “OUTLINES AND GROUPING IN EXCEL”. Adjacent rows with the same outline level are grouped together into a single outline.

The following example sets an outline level of 1 for rows 1 and 2 (zero-indexed):

worksheet.set_row(1, nil, nil, 0, 1)
worksheet.set_row(2, nil, nil, 0, 1)

The hidden parameter can also be used to hide collapsed outlined rows when used in conjunction with the level parameter.

worksheet.set_row(1, nil, nil, 1, 1)
worksheet.set_row(2, nil, nil, 1, 1)

For collapsed outlines you should also indicate which row has the collapsed + symbol using the optional collapsed parameter.

worksheet.set_row(3, nil, nil, 0, 0, 1)

For a more complete example see the outline.rb and outline_collapsed.rb programs in the examples directory of the distro.

Excel allows up to 7 outline levels. Therefore the level parameter should be in the range 0 <= level <= 7.

#set_selection(*args) ⇒ Object

:call-seq:

set_selection(cell_or_cell_range)

Set which cell or cells are selected in a worksheet.

This method can be used to specify which cell or cells are selected in a worksheet. The most common requirement is to select a single cell, in which case last_row and last_col can be omitted. The active cell within a selected range is determined by the order in which first and last are specified. It is also possible to specify a cell or a range using A1 notation. See the note about “Cell notation”.

Examples:

worksheet1.set_selection(3, 3)          # 1. Cell D4.
worksheet2.set_selection(3, 3, 6, 6)    # 2. Cells D4 to G7.
worksheet3.set_selection(6, 6, 3, 3)    # 3. Cells G7 to D4.
worksheet4.set_selection('D4')          # Same as 1.
worksheet5.set_selection('D4:G7')       # Same as 2.
worksheet6.set_selection('G7:D4')       # Same as 3.

The default cell selections is (0, 0), ‘A1’.

#set_tab_color(color) ⇒ Object

Set the colour of the worksheet tab.

#set_v_pagebreaks(*args) ⇒ Object

Store the vertical page breaks on a worksheet.

Add vertical page breaks to a worksheet. A page break causes all the data that follows it to be printed on the next page. Vertical page breaks act between columns. To create a page break between columns 20 and 21 you must specify the break at column 21. However in zero index notation this is actually column 20. So you can pretend for a small while that you are using 1 index notation:

worksheet1.set_v_pagebreaks(20) # Break between column 20 and 21

The set_v_pagebreaks() method will accept a list of page breaks and you can call it more than once:

worksheet2.set_v_pagebreaks( 20,  40,  60,  80,  100 )    # Add breaks
worksheet2.set_v_pagebreaks( 120, 140, 160, 180, 200 )    # Add some more

Note: If you specify the “fit to page” option via the fit_to_pages() method it will override all manual page breaks.

#show_comments(visible = true) ⇒ Object

Make any comments in the worksheet visible.

worksheet.show_comments

Individual comments can be made visible using the visible parameter of the write_comment method (see above):

worksheet.write_comment('C3', 'Hello', :visible => 1)

If all of the cell comments have been made visible you can hide individual comments as follows:

worksheet.show_comments
worksheet.write_comment('C3', 'Hello', :visible => 0)

#split_panes(*args) ⇒ Object

:call-seq:

split_panes(y, x, top_row, left_col, offset_row, offset_col)

Set panes and mark them as split. – Implementers note. The API for this method doesn’t map well from the XLS file format and isn’t sufficient to describe all cases of split panes. It should probably be something like:

split_panes(y, x, top_row, left_col, offset_row, offset_col)

I’ll look at changing this if it becomes an issue. ++ This method can be used to divide a worksheet into horizontal or vertical regions known as panes. This method is different from the freeze_panes() method in that the splits between the panes will be visible to the user and each pane will have its own scroll bars.

The parameters y and x are used to specify the vertical and horizontal position of the split. The units for y and x are the same as those used by Excel to specify row height and column width. However, the vertical and horizontal units are different from each other. Therefore you must specify the y and x parameters in terms of the row heights and column widths that you have set or the default values which are 15 for a row and 8.43 for a column.

You can set one of the y and x parameters as zero if you do not want either a vertical or horizontal split. The parameters top_row and left_col are optional. They are used to specify the top-most or left-most visible row or column in the bottom-right pane.

Example:

worksheet.split_panes(15, 0   )    # First row
worksheet.split_panes( 0, 8.43)    # First column
worksheet.split_panes(15, 8.43)    # First row and column

You cannot use A1 notation with this method.

write(row, column [ , token [ , format ] ])

Excel makes a distinction between data types such as strings, numbers, blanks, formulas and hyperlinks. To simplify the process of writing data the write() method acts as a general alias for several more specific methods:

write_string
write_number
write_blank
write_formula
write_url
write_row
write_col

The general rule is that if the data looks like a something then a something is written. Here are some examples in both row-column and A1 notation:

                                                # Same as:
worksheet.write(0, 0, 'Hello'                ) # write_string()
worksheet.write(1, 0, 'One'                  ) # write_string()
worksheet.write(2, 0,  2                     ) # write_number()
worksheet.write(3, 0,  3.00001               ) # write_number()
worksheet.write(4, 0,  ""                    ) # write_blank()
worksheet.write(5, 0,  ''                    ) # write_blank()
worksheet.write(6, 0,  nil                   ) # write_blank()
worksheet.write(7, 0                         ) # write_blank()
worksheet.write(8, 0,  'http://www.ruby.com/') # write_url()
worksheet.write('A9',  'ftp://ftp.ruby.org/' ) # write_url()
worksheet.write('A10', 'internal:Sheet1!A1'  ) # write_url()
worksheet.write('A11', 'external:c:\foo.xlsx') # write_url()
worksheet.write('A12', '=A3 + 3*A4'          ) # write_formula()
worksheet.write('A13', '=SIN(PI()/4)'        ) # write_formula()
worksheet.write('A14', [1, 2]                ) # write_row()
worksheet.write('A15', [ [1, 2] ]            ) # write_col()

# Write an array formula. Not available in writeexcel gem.
worksheet.write('A16', '{=SUM(A1:B1*A2:B2)}' ) # write_formula()

The format parameter is optional. It should be a valid Format object.

format = workbook.add_format
format.set_bold
format.set_color('red')
format.set_align('center')

worksheet.write(4, 0, 'Hello', format)    # Formatted string

The write() method will ignore empty strings or nil tokens unless a format is also supplied. As such you needn’t worry about special handling for empty or nil in your data. See also the write_blank() method.

One problem with the write() method is that occasionally data looks like a number but you don’t want it treated as a number. For example, zip codes or ID numbers often start with a leading zero. If you want to write this data with leading zero(s), use write_string.

The write methods return:

0 for success.

#write_array_formula(*args) ⇒ Object

:call-seq:

write_array_formula(row1, col1, row2, col2, formula [ , format [ , value ] ] )

Write an array formula to the specified row and column (zero indexed).

format is optional.

In Excel an array formula is a formula that performs a calculation on a set of values. It can return a single value or a range of values.

An array formula is indicated by a pair of braces around the formula: =SUM(A1:B1*A2:B2). If the array formula returns a single value then the first and last parameters should be the same:

worksheet.write_array_formula('A1:A1', '{=SUM(B1:C1*B2:C2)}')

It this case however it is easier to just use the write_formula() or write() methods:

# Same as above but more concise.
worksheet.write('A1', '{=SUM(B1:C1*B2:C2)}')
worksheet.write_formula('A1', '{=SUM(B1:C1*B2:C2)}')

For array formulas that return a range of values you must specify the range that the return values will be written to:

worksheet.write_array_formula('A1:A3',    '{=TREND(C1:C3,B1:B3)}')
worksheet.write_array_formula(0, 0, 2, 0, '{=TREND(C1:C3,B1:B3)}')

If required, it is also possible to specify the calculated value of the formula. This is occasionally necessary when working with non-Excel applications that don’t calculate the value of the formula. The calculated value is added at the end of the argument list:

worksheet.write_array_formula('A1:A3', '{=TREND(C1:C3,B1:B3)}', format, 105)

In addition, some early versions of Excel 2007 don’t calculate the values of array formulas when they aren’t supplied. Installing the latest Office Service Pack should fix this issue.

See also the array_formula.rb program in the examples directory of the distro.

Note: Array formulas are not supported by writeexcel gem.

  end
end

#write_blank(*args) ⇒ Object

:call-seq:

write_blank(row, col, format)

Write a blank cell to the specified row and column (zero indexed). A blank cell is used to specify formatting without adding a string or a number.

A blank cell without a format serves no purpose. Therefore, we don’t write a BLANK record unless a format is specified. This is mainly an optimisation for the write_row() and write_col() methods.

Excel differentiates between an “Empty” cell and a “Blank” cell. An “Empty” cell is a cell which doesn’t contain data whilst a “Blank” cell is a cell which doesn’t contain data but does contain formatting. Excel stores “Blank” cells but ignores “Empty” cells.

As such, if you write an empty cell without formatting it is ignored:

worksheet.write('A1', nil, format )    # write_blank()
worksheet.write('A2', nil )            # Ignored

This seemingly uninteresting fact means that you can write arrays of data without special treatment for nil or empty string values.

See the note about “Cell notation”.

#write_col(*args) ⇒ Object

:call-seq:

write_col(row, col, array [ , format ] )

Write a column of data starting from (row, col). Call write_row() if any of the elements of the array are in turn array. This allows the writing of 1D or 2D arrays of data in one go.

The write_col() method can be used to write a 1D or 2D array of data in one go. This is useful for converting the results of a database query into an Excel worksheet. You must pass a reference to the array of data rather than the array itself. The write() method is then called for each element of the data. For example:

array = [ 'awk', 'gawk', 'mawk' ]

worksheet.write_col(0, 0, array)

# The above example is equivalent to:
worksheet.write(0, 0, array[0])
worksheet.write(1, 0, array[1])
worksheet.write(2, 0, array[2])

As with all of the write methods the format parameter is optional. If a format is specified it is applied to all the elements of the data array.

Array references within the data will be treated as rows. This allows you to write 2D arrays of data in one go. For example:

eec =  [
            ['maggie', 'milly', 'molly', 'may'  ],
            [13,       14,      15,      16     ],
            ['shell',  'star',  'crab',  'stone']
       ]

worksheet.write_col('A1', eec)

Would produce a worksheet as follows:

 -----------------------------------------------------------
|   |    A    |    B    |    C    |    D    |    E    | ...
 -----------------------------------------------------------
| 1 | maggie  | milly   | molly   | may     |  ...    | ...
| 2 | 13      | 14      | 15      | 16      |  ...    | ...
| 3 | shell   | star    | crab    | stone   |  ...    | ...
| 4 | ...     | ...     | ...     | ...     |  ...    | ...
| 5 | ...     | ...     | ...     | ...     |  ...    | ...
| 6 | ...     | ...     | ...     | ...     |  ...    | ...

To write the data in a column-row order refer to the write_row() method above.

Any nil in the data will be ignored unless a format is applied to the data, in which case a formatted blank cell will be written. In either case the appropriate row or column value will still be incremented.

As noted above the write() method can be used as a synonym for write_row() and write_row() handles nested array refs as columns. Therefore, the following two method calls are equivalent although the more explicit call to write_col() would be preferable for maintainability:

worksheet.write_col('A1', array     ) # Write a column of data
worksheet.write(    'A1', [ array ] ) # Same thing

The write_col() method returns the first error encountered when writing the elements of the data or zero if no errors were encountered. See the return values described for the write() method above.

#write_comment(*args) ⇒ Object

:call-seq:

write_comment(row, column, string, options = {})

Write a comment to the specified row and column (zero indexed).

write_comment methods return:

Returns  0 : normal termination

The write_comment() method is used to add a comment to a cell. A cell comment is indicated in Excel by a small red triangle in the upper right-hand corner of the cell. Moving the cursor over the red triangle will reveal the comment.

The following example shows how to add a comment to a cell:

worksheet.write(        2, 2, 'Hello')
worksheet.write_comment(2, 2, 'This is a comment.')

As usual you can replace the row and column parameters with an A1 cell reference. See the note about “Cell notation”.

worksheet.write(        'C3', 'Hello')
worksheet.write_comment('C3', 'This is a comment.')

The write_comment() method will also handle strings in UTF-8 format.

worksheet.write_comment('C3', "\x{263a}")       # Smiley
worksheet.write_comment('C4', 'Comment ca va?')

In addition to the basic 3 argument form of write_comment() you can pass in several optional key/value pairs to control the format of the comment. For example:

worksheet.write_comment('C3', 'Hello', :visible => 1, :author => 'Perl')

Most of these options are quite specific and in general the default comment behaviour will be all that you need. However, should you need greater control over the format of the cell comment the following options are available:

:author
:visible
:x_scale
:width
:y_scale
:height
:color
:start_cell
:start_row
:start_col
:x_offset
:y_offset

Option: author

This option is used to indicate who is the author of the cell comment. Excel displays the author of the comment in the status bar at the bottom of the worksheet. This is usually of interest in corporate environments where several people might review and provide comments to a workbook.

worksheet.write_comment('C3', 'Atonement', :author => 'Ian McEwan')

The default author for all cell comments can be set using the set_comments_author() method.

worksheet.set_comments_author('Ruby')

Option: visible

This option is used to make a cell comment visible when the worksheet is opened. The default behaviour in Excel is that comments are initially hidden. However, it is also possible in Excel to make individual or all comments visible. In WriteXLSX individual comments can be made visible as follows:

worksheet.write_comment('C3', 'Hello', :visible => 1 )

It is possible to make all comments in a worksheet visible using the show_comments() worksheet method. Alternatively, if all of the cell comments have been made visible you can hide individual comments:

worksheet.write_comment('C3', 'Hello', :visible => 0)

Option: x_scale

This option is used to set the width of the cell comment box as a factor of the default width.

worksheet.write_comment('C3', 'Hello', :x_scale => 2)
worksheet.write_comment('C4', 'Hello', :x_scale => 4.2)

Option: width

This option is used to set the width of the cell comment box explicitly in pixels.

worksheet.write_comment('C3', 'Hello', :width => 200)

Option: y_scale

This option is used to set the height of the cell comment box as a factor of the default height.

worksheet.write_comment('C3', 'Hello', :y_scale => 2)
worksheet.write_comment('C4', 'Hello', :y_scale => 4.2)

Option: height

This option is used to set the height of the cell comment box explicitly in pixels.

worksheet.write_comment('C3', 'Hello', :height => 200)

Option: color

This option is used to set the background colour of cell comment box. You can use one of the named colours recognised by WriteXLSX or a colour index. See “COLOURS IN EXCEL”.

worksheet.write_comment('C3', 'Hello', :color => 'green')
worksheet.write_comment('C4', 'Hello', :color => 0x35)      # Orange

Option: start_cell

This option is used to set the cell in which the comment will appear. By default Excel displays comments one cell to the right and one cell above the cell to which the comment relates. However, you can change this behaviour if you wish. In the following example the comment which would appear by default in cell D2 is moved to E2.

worksheet.write_comment('C3', 'Hello', :start_cell => 'E2')

Option: start_row

This option is used to set the row in which the comment will appear. See the start_cell option above. The row is zero indexed.

worksheet.write_comment('C3', 'Hello', :start_row => 0)

Option: start_col

This option is used to set the column in which the comment will appear. See the start_cell option above. The column is zero indexed.

worksheet.write_comment('C3', 'Hello', :start_col => 4)

Option: x_offset

This option is used to change the x offset, in pixels, of a comment within a cell:

worksheet.write_comment('C3', comment, :x_offset => 30)

Option: y_offset

This option is used to change the y offset, in pixels, of a comment within a cell:

worksheet.write_comment('C3', comment, :x_offset => 30)

You can apply as many of these options as you require.

Note about using options that adjust the position of the cell comment such as start_cell, start_row, start_col, x_offset and y_offset: Excel only displays offset cell comments when they are displayed as “visible”. Excel does not display hidden cells as moved when you mouse over them.

Note about row height and comments. If you specify the height of a row that contains a comment then WriteXLSX will adjust the height of the comment to maintain the default or user specified dimensions. However, the height of a row can also be adjusted automatically by Excel if the text wrap property is set or large fonts are used in the cell. This means that the height of the row is unknown to the module at run time and thus the comment box is stretched with the row. Use the set_row() method to specify the row height explicitly and avoid this problem.

#write_date_time(*args) ⇒ Object

:call-seq:

write_date_time (row, col, date_string [ , format ] )

Write a datetime string in ISO8601 “yyyy-mm-ddThh:mm:ss.ss” format as a number representing an Excel date. format is optional.

The write_date_time() method can be used to write a date or time to the cell specified by row and column:

worksheet.write_date_time('A1', '2004-05-13T23:20', date_format)

The date_string should be in the following format:

yyyy-mm-ddThh:mm:ss.sss

This conforms to an ISO8601 date but it should be noted that the full range of ISO8601 formats are not supported.

The following variations on the date_string parameter are permitted:

yyyy-mm-ddThh:mm:ss.sss         # Standard format
yyyy-mm-ddT                     # No time
          Thh:mm:ss.sss         # No date
yyyy-mm-ddThh:mm:ss.sssZ        # Additional Z (but not time zones)
yyyy-mm-ddThh:mm:ss             # No fractional seconds
yyyy-mm-ddThh:mm                # No seconds

Note that the T is required in all cases.

A date should always have a format, otherwise it will appear as a number, see “DATES AND TIME IN EXCEL” and “CELL FORMATTING”. Here is a typical example:

date_format = workbook.add_format(:num_format => 'mm/dd/yy')
worksheet.write_date_time('A1', '2004-05-13T23:20', date_format)

Valid dates should be in the range 1900-01-01 to 9999-12-31, for the 1900 epoch and 1904-01-01 to 9999-12-31, for the 1904 epoch. As with Excel, dates outside these ranges will be written as a string.

worksheet.write_formula(1, 0, '=SIN(PI()/4)')
worksheet.write_formula(2, 0, '=SUM(B1:B5)')

See the note about “Cell notation”. For more information about writing Excel formulas see “FORMULAS AND FUNCTIONS IN EXCEL”

If required, it is also possible to specify the calculated value of the formula. This is occasionally necessary when working with non-Excel applications that don’t calculate the value of the formula. The calculated value is added at the end of the argument list:

worksheet.write('A1', '=2+2', format, 4)

However, this probably isn’t something that will ever need to do. If you do use this feature then do so with care.

worksheet.write_number('A2', 2.3451)

See the note about “Cell notation”. The format parameter is optional.

In general it is sufficient to use the write() method.

Note: some versions of Excel 2007 do not display the calculated values of formulas written by WriteXLSX. Applying all available Service Packs to Excel should fix this.

#write_rich_string(*args) ⇒ Object

:call-seq:

write_rich_string(row, column, (string | format, string)+,  [,cell_format] )

The write_rich_string() method is used to write strings with multiple formats. The method receives string fragments prefixed by format objects. The final format object is used as the cell format.

write_rich_string methods return:

For example to write the string “This is bold and this is italic” you would use the following:

bold   = workbook.add_format(:bold   => 1)
italic = workbook.add_format(:italic => 1)

worksheet.write_rich_string('A1',
    'This is ', bold, 'bold', ' and this is ', italic, 'italic')

The basic rule is to break the string into fragments and put a format object before the fragment that you want to format. For example:

# Unformatted string.
  'This is an example string'

# Break it into fragments.
  'This is an ', 'example', ' string'

# Add formatting before the fragments you want formatted.
  'This is an ', format, 'example', ' string'

# In WriteXLSX.
worksheet.write_rich_string('A1',
    'This is an ', format, 'example', ' string')

String fragments that don’t have a format are given a default format. So for example when writing the string “Some bold text” you would use the first example below but it would be equivalent to the second:

# With default formatting:
bold    = workbook.add_format(:bold => 1)

worksheet.write_rich_string('A1',
    'Some ', bold, 'bold', ' text')

# Or more explicitly:
bold    = workbook.add_format(:bold => 1)
default = workbook.add_format

worksheet.write_rich_string('A1',
    default, 'Some ', bold, 'bold', default, ' text')

As with Excel, only the font properties of the format such as font name, style, size, underline, color and effects are applied to the string fragments. Other features such as border, background and alignment must be applied to the cell.

The write_rich_string() method allows you to do this by using the last argument as a cell format (if it is a format object). The following example centers a rich string in the cell:

bold   = workbook.add_format(:bold  => 1)
center = workbook.add_format(:align => 'center')

worksheet.write_rich_string('A5',
    'Some ', bold, 'bold text', ' centered', center)

See the rich_strings.rb example in the distro for more examples.

bold   = workbook.add_format(:bold        => 1)
italic = workbook.add_format(:italic      => 1)
red    = workbook.add_format(:color       => 'red')
blue   = workbook.add_format(:color       => 'blue')
center = workbook.add_format(:align       => 'center')
super  = workbook.add_format(:font_script => 1)

# Write some strings with multiple formats.
worksheet.write_rich_string('A1',
    'This is ', bold, 'bold', ' and this is ', italic, 'italic')

worksheet.write_rich_string('A3',
    'This is ', red, 'red', ' and this is ', blue, 'blue')

worksheet.write_rich_string('A5',
    'Some ', bold, 'bold text', ' centered', center)

worksheet.write_rich_string('A7',
    italic, 'j = k', super, '(n-1)', center)

As with write_sting() the maximum string size is 32767 characters. See also the note about “Cell notation”.

#write_row(*args) ⇒ Object

:call-seq:

write_row(row, col, array [ , format ] )

Write a row of data starting from (row, col). Call write_col() if any of the elements of the array are in turn array. This allows the writing of 1D or 2D arrays of data in one go.

The write_row() method can be used to write a 1D or 2D array of data in one go. This is useful for converting the results of a database query into an Excel worksheet. You must pass a reference to the array of data rather than the array itself. The write() method is then called for each element of the data. For example:

array = ['awk', 'gawk', 'mawk']

worksheet.write_row(0, 0, array)

# The above example is equivalent to:
worksheet.write(0, 0, array[0])
worksheet.write(0, 1, array[1])
worksheet.write(0, 2, array[2])

Note: For convenience the write() method behaves in the same way as write_row() if it is passed an array reference. Therefore the following two method calls are equivalent:

worksheet.write_row('A1', array)    # Write a row of data
worksheet.write(    'A1', array)    # Same thing

As with all of the write methods the format parameter is optional. If a format is specified it is applied to all the elements of the data array.

Array references within the data will be treated as columns. This allows you to write 2D arrays of data in one go. For example:

eec =  [
            ['maggie', 'milly', 'molly', 'may'  ],
            [13,       14,      15,      16     ],
            ['shell',  'star',  'crab',  'stone']
       ]

worksheet.write_row('A1', eec)

Would produce a worksheet as follows:

 -----------------------------------------------------------
|   |    A    |    B    |    C    |    D    |    E    | ...
 -----------------------------------------------------------
| 1 | maggie  | 13      | shell   | ...     |  ...    | ...
| 2 | milly   | 14      | star    | ...     |  ...    | ...
| 3 | molly   | 15      | crab    | ...     |  ...    | ...
| 4 | may     | 16      | stone   | ...     |  ...    | ...
| 5 | ...     | ...     | ...     | ...     |  ...    | ...
| 6 | ...     | ...     | ...     | ...     |  ...    | ...

To write the data in a row-column order refer to the write_col() method below.

Any nil in the data will be ignored unless a format is applied to the data, in which case a formatted blank cell will be written. In either case the appropriate row or column value will still be incremented.

The write_row() method returns the first error encountered when writing the elements of the data or zero if no errors were encountered. See the return values described for the write() method.

#write_string(*args) ⇒ Object

:call-seq:

write_string(row, column, string [, format ] )

Write a string to the specified row and column (zero indexed). format is optional.

worksheet.write_string(0, 0, 'Your text here')
worksheet.write_string('A2', 'or here')

The maximum string size is 32767 characters. However the maximum string segment that Excel can display in a cell is 1000. All 32767 characters can be displayed in the formula bar.

In general it is sufficient to use the write() method. However, you may sometimes wish to use the write_string() method to write data that looks like a number but that you don’t want treated as a number. For example, zip codes or phone numbers:

# Write as a plain string
worksheet.write_string('A1', '01209')

However, if the user edits this string Excel may convert it back to a number. To get around this you can use the Excel text format @:

# Format as a string. Doesn't change to a number when edited
format1 = workbook.add_format(:num_format => '@')
worksheet.write_string('A2', '01209', format1)

#write_url(*args) ⇒ Object

:call-seq:

write_url(row, column, url [ , format, string, tool_tip ] )

Write a hyperlink to a URL in the cell specified by row and column. The hyperlink is comprised of two elements: the visible label and the invisible link. The visible label is the same as the link unless an alternative label is specified. The label parameter is optional. The label is written using the write() method. Therefore it is possible to write strings, numbers or formulas as labels.

The hyperlink can be to a http, ftp, mail, internal sheet, or external directory url.

The format parameter is also optional, however, without a format the link won’t look like a format.

The suggested format is:

format = workbook.add_format(:color => 'blue', :underline => 1)

Note, this behaviour is different from writeexcel gem which provides a default hyperlink format if one isn’t specified by the user.

There are four web style URI’s supported:

http://, https://, ftp:// and mailto

worksheet.write_url(0, 0, ‘www.ruby.org/’, format) worksheet.write_url(1, 0, ‘www.ruby.com/’, format, ‘Ruby’) worksheet.write_url(‘A3’, ‘www.ruby.com/’, format) worksheet.write_url(‘A4’, ‘[email protected]’, format)

There are two local URIs supported: internal: and external:. These are used for hyperlinks to internal worksheet references or external workbook and worksheet references:

worksheet.write_url('A6',  'internal:Sheet2!A1',              format)
worksheet.write_url('A7',  'internal:Sheet2!A1',              format)
worksheet.write_url('A8',  'internal:Sheet2!A1:B2',           format)
worksheet.write_url('A9',  %q{internal:'Sales Data'!A1},      format)
worksheet.write_url('A10', 'external:c:\temp\foo.xlsx',       format)
worksheet.write_url('A11', 'external:c:\foo.xlsx#Sheet2!A1',  format)
worksheet.write_url('A12', 'external:..\foo.xlsx',            format)
worksheet.write_url('A13', 'external:..\foo.xlsx#Sheet2!A1',  format)
worksheet.write_url('A13', 'external:\\\\NET\share\foo.xlsx', format)

All of the these URI types are recognised by the write() method, see above.

Worksheet references are typically of the form Sheet1!A1. You can also refer to a worksheet range using the standard Excel notation: Sheet1!A1:B2.

In external links the workbook and worksheet name must be separated by the # character: external:Workbook.xlsx#Sheet1!A1’.

You can also link to a named range in the target worksheet. For example say you have a named range called my_name in the workbook c:tempfoo.xlsx you could link to it as follows:

worksheet.write_url('A14', 'external:c:\temp\foo.xlsx#my_name')

Excel requires that worksheet names containing spaces or non alphanumeric characters are single quoted as follows ‘Sales Data’!A1.
