Hmm, sounds interesting, I've always resorted to using CSV (or even HTML!) when exporting to Excel.
As far as how to open it up, have a look at creating a project on www.sourceforge.net or just zip it up and bung it on your own website if you have one. I've got the feeling there are also Python-specific repositories too. Or you could just paste the code into a blog or something free like Livejournal. Good luck on the France thing, that's where my folks live now (I'm an Englishman who retreated to the US!) -- http://mail.python.org/mailman/listinfo/python-list
