I'm working on a way to translate terms via google but I can't seem to find a way to acces all the keys in the translation manager to iterate through them & update them.
Hello. Translation manager entries can be exported but I believe the file format is xml which is very cumbersome. There are multiple requests out in the features forums to make the translation manager easier to work with and to support more widely use import and export files like csv.
