Bad news. The server hosting The Ruby Toolbox went bust on the evening of June 7th. While I do have backups, the original source code is in a very outdated state so I currently don't feel it makes sense to try and get it running again.

For the time being, here is a very stripped down version of the Ruby Toolbox's contents.

Update June 13th: I'd like to invite you to join the discussion on the future of the Toolbox on github. You can also get in touch directly on Twitter.

axlsx

xlsx spreadsheet generation with charts, images, automated column width, customizable styles and full schema validation. Axlsx helps you create beautiful Office Open XML Spreadsheet documents ( Excel, Google Spreadsheets, Numbers, LibreOffice) without having to understand the entire ECMA specification. Check out the README for some examples of how easy it is. Best of all, you can validate your xlsx file before serialization so you know for sure that anything generated is going to load on your client's machine.
