I know it's possible, cause google docs' spreadsheet app does it. I just don't know how difficult it will be. Does anyone have any ideas?
If you really want to read from Excel then there are two not so bad ways to go. If you really want to do this client side then use an HTA (HTML Application). That will only run in MSIE but with all the security down so it can read files. Better would be to have them upload the Excel to a server side script. As long as your server is running Windows and has the Jet and Excel installed then reading the files would be a snap.

Hi Charles, thanks for the reply! I'm trying to keep this as platform independent as possible, so I don't really like any of your suggestions (sorry). I also want it to be as drag 'n' drop friendly and copy/paste friendly as possible.
