yeah xml is excel format.
He use xml ive upload the file. I test it with Crowdin.net but there goes something wrong and some metadata gets lost.
I dont know is it possible to change the xml complete to a new format like openxcom without a lot of work?
So i see how easy it is with openxcom on getlocalization.com
Or is there another way? The support of getlocalization.com allready know about that but they change nothing or do something.
