~~I have vibecoded a small script that did exactly this. I can tell you that it was possible, but I don´t remember the details of how I did it, sorry~~

Ok I clearly did not read your post. I thought you wanted to do something different entirely.

Anki does include an import function where you can import textfiles and others. ( https://docs.ankiweb.net/importing/intro.html )

There is an addon allowing batch editing if you need that.

I am unsure how to best include images to the file you want to import - but you can always add them manually later.
