I don't believe that any application outside of Excel is going to behave this way. Try it on a real server and see what happens. I think you can replace the file right out from under the process, then tell it to re-import, and you should be good. But test it out to be sure. Just don't take anything Excel has to say about this as meaningful in the context of your production server.

If this does prove to be a problem, then just rename the file on the server as you save it. Append the current time in milliseconds or something similar to cause it to have an unique name on disk. Or delete the file on your server after you have read it into your database. You won't need it after you've parsed it into database records, after all.
