A Ruby library for reading, writing, and modifying Microsoft Excel (XLS) spreadsheet documents. It is a rewrite of the Spreadsheet::Excel and ParseExcel libraries and supports only the legacy XLS binary format, not XLSX.

Use cases

  • read data from xls files in ruby
  • generate excel reports from ruby
  • modify existing xls spreadsheets programmatically
  • parse legacy excel 97-2003 files
  • hide or group rows and columns in excel files
  • process large excel files with low memory usage

When to choose

  • you need to read or write legacy XLS (BIFF) files in Ruby
  • you need to modify existing Excel documents including outline/grouping features
  • you work with Ruby 2.6+ or JRuby and want a pure-Ruby spreadsheet library

When to avoid

  • you need XLSX (Open XML) support - this library only handles XLS
  • you need formula reading/writing or full style support, which are still on the roadmap
  • you cannot use GPLv3 and cannot obtain a commercial license
  • you need cell format fidelity - number formats may be lost and returned as floats
