Detecting language please wait for.......
Or do I just have to save each one individually and then load and run them one by one?
You can find this functionality in this paid app:
Batch search & replace is one of the tools available…
CleanUp Tasks should also work for you: https://appstore.sdl.com/language/app/cleanup-tasks/963/
Thanks Daniel Hug... considering we now own this app I'd never thought about using it for a simple search & replace! Think I need to take a step back and look for the easier solutions!
Why not use SDLXLIFF Toolkit?
Can you do batch search and replace operations with that?
Oh, sorry - no, not batch. I've overseen the "batch" request here.
