I don't know if there was a real NEED for this out there.
I gave it a test using Nav's Country Codes.
Only allows 100 lines a sheet so it's 3 sheets (see bottom)http://spreadsheets.google.com/ccc?key= ... ZqUuH-DbMQ
Useful or useless?
Maybe it's their first step to creating an Online Google Office Suite that everyone can use and share files easily.
ps I think you need a google account to see it - let me know.
