What about JSON to CSV? I am trying to create my custom league using the same rating ranges as the '18 version. I noticed the CPU-generated Ratings are much higher in the 18 version than that of the 16 version. I would like to use those, as for instance my CPU-generated league in '16 only had like 5 people in the 90's OVERALL ratings, whereas there were like 20+ in '18.
Does this make sense? I'm not sure why the CPU-generated ratings are different between the two versions, but I assume I should base my own created players on the '18 ratings.
