csv format?
 

i was just wondering how come everytime i try to edit a player file and then try an save it it says its not in csv format anymore? How would i be able to edit it(i.e. add players and cahnge players ratings) while keeping it in csv and being able yo use it?

What program are you using to edit it? If it's excel and you're saving as an xls file, then yeah, it would no longer be a csv file. Just do a save as in Excel in csv format, and you should be fine.
