Best way to generate complex spreadsheets with rails


  We are developing a rails app where the generation of complex excel
documents is necessary. By complex I mean a spreadsheet with formulas,
including cross-file and cross-tab references.
  The only ruby component we've found is way too simple to what we need.
  What do you recomend?

  Really apreciate your help.


Is JRuby an option? There is a great Java library called POI for doing what you need.
