Excel might help--I've been using it a lot to do mass-stuff lately--use _ as a divide, and then just re-arrange the columns, drop it into notepad++ and replace "[space]" with "_"
Ugh, that sounds like an annoying way to fix it especially since I can't use Excel (1. No License 2. I No Windows 3. I don't actually know how to use it). I'll just write a script to do it for me - or even better, I'm writing another automation tool that will generate these namelists for many cultures in a scalable manner (I think a program that does that exists but I wanted to make one that doesn't care about the existence of 00_cultures.txt and doesn't rely on a platform-specific compiler).
Do you know if I can have multiple variations of the same name in a single culture though? That will be really helpful when making this tool.
