"Always remove"? Really? Always? Even when you use ExcelDirect from the Financial Reporter? GridView?

You can have the ExcelDirect button generate a CSV, which will have no formatting at all when loaded into Excel. Is that what you're looking for? Have you checked how to set the default Template in Excel? (Use Google).

If I knew the specific task you were trying to perform, I would be able to give better advice about how to accomplish this using Adagio.
