I would recommend using the .xlsm files and using the All.xlsm to generate the .txt files needed. With this approach you won't have to worry about formatting and it's much easier to find and modify the things you need, especially if you are doing a lot of stat modifications.

Some people complain that the generation is slow, but its much quicker if you delete all the data originally in the file. They will still be in the game because they are in the main mod which is always a dependency. If you want to only re-generate one file you can also just run the generate() macro directly from that page.

Item combos is actually generated separately form All the others so it for some reason stores it in the same file rather then the generated file.
