Feature Request : Add Support for JSON document translation

Description
The user would be able to upload a JSON document for translation.
DeepL systems would recursively process the nested objects util a string is found, translate the string and create the output file without changing the keys or the document structure.

Original issue by @itsChiragKapoor. I messed up the issue transfer, sorry

Our API does not currently support this. We provide a code example how to do this in python here.

For your use case, would you find a feature useful that allows you to specify keys you don't want to translate (blacklist)/list the only keys you want to translate (whitelist)?
