dullard

Super simple, super fast stream-based XLSX parsing. Suitable for very large files.

Requires Ruby 2.0.

require 'dullard' 

workbook = Dullard::Workbook.new "file.xlsx"
workbook.sheets[0].rows.each do |row|
  p row # => ["a","b","c", 0.3, #<DateTime: -4712-01-01....>, ...]
end

Current limitations

• Limited validation and error handling.
• Formatted cells are read, but formatting is not accessible.
• May be buggy. Pull requests welcome!
• Rows that end with empty cells may be truncated.
