I now have a fully translated (into Danish) Ubercart Backdrop store thanks to ChatGPT - the free version. I only see very few 'glitches' - in general much better than I could do - well, unless I had 'all the time in the world'. I would not have been able to this in a month - ChatGPT took about two hours!.
Just awaiting response whether I can upload my translated .po file to the Backdrop language server without creating problems (it is 'polluted' by module translations).
The ChatGT just need to know it is supposed to translate a .po file from english to ??? (your language) in accordance with GNU gettext.

Here's the .po file for ubercart alone (only the strings for that module, unstranslated):
