in reply to Open viewable excel file

You are writing the excel file to disk after editing, aren't you? Bind the button to view the excel file to a subroutine that invokes a command to open that file.

For Microsoft that is (if I remeber well) system "start \"$excelfile\""; on unixes you might be able to use system "oocalc '$excelfile'" (or applix instead of oocalc, or ..., whatever).
