Hi
I am kind of stuck:
I change my music server, that's why I need to to copy the contents of my (filled) "SOLOIST" tag to the (empty) "ARTIST" tag. Concerned are thousands of tracks. How can I handle this? I read the instructions on the batch operations, however, since I am new to MP3TAG, it is kind of confusing for me...
Any help would be much appreciated!

> 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,\\\\)

Thanks! I use \ as seperator for the values in SOLOIST, so I would use:
Action type: Format value
Field: ARTIST
Format string: **$meta\_sep(soloist,\)**
Right?

No.
The $meta\_sep() function is intended only for real multi-value fields (the same type of field but several of them). So before you use that function, check the extended tags dialogue (alt-T) if you really have several fields of the type SOLOIST or just one.
If there is just one SOLOIST, it would be
Format string: %soloist%

Hi,
I have used $meta\_sep(soloist,) and it's working out great. Now, I want to include the conductor. In other words, the field ARTIST is supposed to show soloist and conductor (has separate CONDUCTOR tag).
How can I do this?

Use an action of the type "Format value" for ARTIST
Format string: %artist% / %conductor%
