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
