The Spreadsheet Library is designed to read and write Spreadsheet Documents. As of version 0.6.0, only Microsoft Excel compatible spreadsheets are supported. Spreadsheet is a combination/complete rewrite of the Spreadsheet::Excel Library by Daniel J. Berger and the ParseExcel Library by Hannes Wyss. Spreadsheet can read, write and modify Spreadsheet Documents.

• Alfred: The library doesn't recognize cell formats in Excel created documents, which results in Floats returned for any number.
• Tom: This library only supports XLS format; it does not support XLSX format.

• Supported outline (grouping) functions
• Significantly improved memory-efficiency when reading large Excel Files
• Limited Spreadsheet modification support
• Improved handling of String Encodings

• Improved Format support/Styles
• Document Modification: Formats/Styles
• Formula Support
• Document Modification: Formulas
• Write-Support: BIFF5
• Remove backward compatibility code

Note: Spreadsheet is tested against all minor ruby versions through: 1.8.7 - 2.6.3

You will get a deprecated warning about iconv when using spreadsheet with Ruby 1.9.3. So replacing iconv is on the Roadmap as well ;).
