Hello,

![:book:](https://community.mp3tag.de/uploads/default/original/1X/0036d5b68f6226c53f6c68abfd0a7b8096fd4505.gif ":book:") I have been studying regex syntax today like crazy but cannot figure this one out...

I have my ARTIST tags in the following format:

ArtistFirstName ArtistLastName, AdditionalArtistFirstName AdditionalArtistLastName, etc

I want to create the ARTISTSORT tag with the value as follows:

ArtistLastName, ArtistFirstName; AdditionalArtistLastName, AdditionalArtistFirstName; etc

Typically the ARTIST tag will contain only a single name, but often I have multiple names so ideally the conversion should be able to handle both cases.

Based on this thread [Multiple value artist tag to multiple value artistsort](https://community.mp3tag.de/t/12599/1) I have copied the %artist% tag into the ARTISTSORT tag but am not getting correct results with the replace with regex action.

Any help would be appreciated.

Thanks!
