If you just want to change the format it works. If you need more than programming skills it seems too fail duo to the amount of text.
E.g. if you have a list of items and want ChatGPT to generate a meta field which it cannot generate using simple python code it stops after 10 to 20 elements.
Thus at least the cloud version doesn't work so well here.
I also wanted it to help me fill out my i18n file with translations and plural forms. Even thought he got every word correct i needed to split it into multiple requests. Not sure if the api would have worked better (used the web frontend).
For the plural forms I finally added them myself as it was way faster for my natural language than copy pasting all the small chunks. Really hoped for more help there.
