This mod will automatically save exported product and/or category tab delimited files with a .tsv suffix instead of .csv. It knows from the data which type to use. This will let you know at-a-glance whether the file is comma separated or tab separated.
It can also come in handy if you use an external app, like FileMaker Pro or Excel, that handles the importing of csv and tsv files differently.
