My users will update their Excel to my system and I will get some information from it, I know the gem that named "win32OLE" on windows is run well, but my system is ubuntu, so how can I operate it?
The Ruby Spreadsheet gem will work for you https://rubygems.org/gems/spreadsheet
You can have a look at roo and parseescelas well.
