Version of Excel

What would you say is the earliest version of microsoft office (excel) should I purchase to work with marketfeeder for many a year, don't really fancy purchasing one which I need to renew each year unless later versions of marketfeeder will only link to later versions of excel.

Excel isn't manadatory. Just use a csv file.

Yes, Excel is not mandatory, but if you need it the 2003 is the earliest tested.

Thanks for telling me 2003 is the minimum version, thank you for that (normally just used open office)

Csv files seems only for import not export or am I wrong?
