I am assuming that your EXE is already compiled and doesn't support piped data (already mentioned as a good method). I am also assuming that the EXE works with the CSV from either a known location or a location passed on the command line. You can always run the EXE from a CMD file that executes your Perl App first before running your EXE. The Perl app simply writes the CSV file to a location that is known to the EXE.

You can even play around with the Windows shortcut that launches the app so that the icon looks like the original EXE's. The users will see the CMD window for the duration of the Perl scripts execution.
