Instance Attribute Details

#font_sizes ⇒ Object (readonly)

This attribute contains effective font widths used for automatic column widths of workbook columns.

Class Method Details

.XlsxWriter::Workbook.new(path, constant_memory: false, tmpdir: nil) ⇒ Object .XlsxWriter::Workbook.new(path, constant_memory: false, tmpdir: nil) {|wb| ... } ⇒ nil .XlsxWriter::Workbook.open(path, constant_memory: false, tmpdir: nil) {|wb| ... } ⇒ nil

Creates a new Xlsx workbook in file path and returns a new Workbook object.

If constant_memory is set to true workbook data is stored in temporary files in tmpdir, considerably reducing memory consumption for large documents.

XlsxWriter::Workbook.open('/tmp/test.xlsx', constant_memory: true) do |wb|
# ... populate the workbook with data ...
end

Overloads:

  • .XlsxWriter::Workbook.new(path, constant_memory: false, tmpdir: nil) {|wb| ... } ⇒ nil

    Yields:

    • (wb)

    Returns:

    • (nil)
  • .XlsxWriter::Workbook.open(path, constant_memory: false, tmpdir: nil) {|wb| ... } ⇒ nil

    Yields:

    • (wb)

    Returns:

    • (nil)
