Replace a field from other fields

Since Spotify detects local files artist field for multiple times, but on phone version it only detects as one...
Like the pic, and it made me need to add the same file to playlist separately on pc and mobile...


But I found that if I replace the album artist field from the artist field, it will work normally, so I'm wondering if there are any ways to do what I said with multiple files in a time?(cuz I don't want to replace them one by one, it will cost me too much time)

Shit there's actually a feature called convert, and it can do what I said, just figured out how to use it, my bad lol

It would have been nice to see or read which function you used with which parameters.

There is, BTW, a post in the FAQs about copying one field to another:
