Edit & Email an Excel Spreadsheet in Rails 2.0

Dear Group,

I hope someone out there can help me with this.

I am building a Rails 2.0 application for a customer. The customer has a number of Excel spreadsheets which he would like his customers to open and complete online then submit the completed spreadsheet to him via email.

A typical scenario would be:

(1) The 'empty' spreadsheets are provided as a list on the web site.

(2) A user clicks on one of the spreadsheets and it opens in the browser.

(3) The user enters data into the spreadsheet.

(4) The user submits the completed spreadsheet to my customer via email (i.e., as an attachment to an email message).

Is anyone aware of any sample code | plugins that would enable me to provide this capability?

Thanks in advance.
