Klixen I don't see that as an issue. In this case you simply make a copy of Main.Pak, never needing to touch the one the game uses. Unpack it, then go into character.xlsm with ecxel, you'll see the where to change it in the spreadsheet. Then you save that. Run All.xlsm, click generate. It creates actual data files from the spreadsheets. Then you place this folder Stats into where you place mods. So in this case no original file is ever messed with.
