I didn't test this code, but looking at the api it looks like Workbook#write will take an IO stream. require 'stringio' require 'spreadsheet' book = Spreadsheet::Workbook.new blob = StringIO.new("") book.write blob send_data blob Be sure to checkout the link below on send_data, it will allow you to transfer the stream of data without writing it to disk first. http://api.rubyonrails.org/classes/ActionController/Streaming.html#M000402 Michael Guterl -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
