Question

I am using this Spreadsheet gem to export xls file.

I have the following codes in my controller:

You can send it to the browser without saving it as a local file at all as follows

spreadsheet = StringIO.new 
book.write spreadsheet 
send_data spreadsheet.string, :filename => "yourfile.xls", :type =>  "application/vnd.ms-excel"
