That didn't seem right, so I tried it and duly got an error. I know
that you can export a Table or a Query as a spreadsheet, but I don't
think you can export a Report in this format. This limitation makes a
certain amount of sense, because Tables and Queries share the concept
of rows (Records) and columns (Fields) with spreadsheets, but Reports
generally don't.
I think the OP needs to be a bit more specific about what he is trying
to get into a spreadsheet.
