Editable Excel Spreadsheet Online?
 

Hi,


I tried to recent find information on this, but could find very
little. How difficult would it be to host an excel spreadsheet online
where visitors to the site can directly view and edit it?

Right now, I can upload the spreadsheet to our web site and visitors
can view it, but if they edit it, they can only save it to their local
drive. I would like the users to be able to save the copy on the
server.

What would be involved in something like this? I assume for starters
(if it's do-able) we'd need Windows hosting (we're not hosting
ourselves) and some ASP support. Any details would be greatly
appreciated.
