I am trying to use either an Excel spreadsheet as an
insertable object or the spreadsheet web components
control to load an Excel file.

I then need to save the changes made in the spreadsheet
control back into the file. This must include all
formatting as well as text.

Can anyone help me with this? I have not been able to
find a way of setting the source of the control to an
Excel file, but surely this is possible!?
