Storing and Updating Excell sheet from a document on web

Hi,I have a customer requirement where they want n no of users to update a single Excel sheet which should be available on their intranet.

I have created a database which contains a document containing the excel sheet as an attachment.

Now when a users edits this document and clicks on the excel sheet, it opens the excel and allows user to modify the excel sheet.

Now my question is how to save the modified excel sheet back in domino document without saving it on the user desk and attaching it again.

Anyone who has faced this situation before and have any ideas, pls let me know.

Thanks,

Anu
