Create .dictionary file from .txt or other method

[AGANG]

Hi Guys!

I already have a hungarian-english and english-hungarian dictionary, which is working fine with the original dictionary app (file extension: .dictionary).
I would like to have a german-hungarian and hungarian-german dictionary too, but I've not found this type of dictionary file yet.
I have already two .txt file (germ-hun and hun-germ; you can download it from: https://www1.dict.cc/translation_file_request.php), which contain the words and meanings.

Is there any solution convert the .txt file into .dictionary file, which I can paste under /Library/Dictionaries folder?

Thank you very much for your help in advance.

You can use for example pyglossary. Once the AppleDict source XML is generated, use the Apple Dictionary Development Kit XCode Auxiliary Tools to generate the native binary files that the Dictionary.app can use.

EDIT: to download the XCode Auxiliary Tools a free Apple Developer is required. Here you find more detailed information about the whole process.

EDIT II: how to install XCode command line tools on Big Sur.
