It's hard to know what some of the values mean in the text files as there's no explanation.
The excel sheets are where the information is contained.
steam\SteamApps\common\Divinity - Original Sin\Data\Editor\Templates\Stats
It's much easier to read, understand and it has value lists, examples, colors.
You can generate the .txt files from the excel sheet you modify OR modify the .txt sheets themselves and use the excel sheet as reference, up to you.
It's a rainbow of pleasure!
