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)

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:

> How to copy one field value to another field? Example how to copy the content of the ARTIST field to the ALBUMARTIST field: Create a [new action](https://community.mp3tag.de/t/actions/967/2) in an existing action group or make a new action group. Action type: Format value Field: ALBUMARTIST Format string: %artist% Note: If you want to copy all possible values of a field (in case you have multiple artist fields), the internal scripting function [$meta\_sep](https://docs.mp3tag.de/scripting) can be used in the format string, e.g., $meta\_sep(artist,\\\\)
