Hello,
In my export configuration, I have the following
$loop(%artist%,1) %artist%,$loopend()
$loop(%mixartist%,1) %mixartist%,$loopend()
But for some reason, it creates commas before and after the data like below
Artist: ,artist1, artist2,
Remixer: ,artist3, artist4,
How can I make it simple like below:
Artist: artist1, artist2
Remixer: artist3, artist4

there must be something else in this export script because when I use that snippet, I get a long list of artists, all separated by a comma - no leading commas. Or there are files where the artist is missing. Same applies the field mixartist: the empty one will be the first in the list.

Here is my export file
```
$filename(txt,utf-8)
%album%
$loop(%artist%,1) %artist% $loopend()
REMIXERS: $loop(%mixartist%,1) %mixartist% $loopend()
%publisher% - %genre%
```
But on Various Artist albums, all artist generated without separated by commas
Arude Binaryh Blancah Clawz SG Jobe Kris Davis Mashk Nick Devon Soul Button Soul Button, Nick Devon
I want to see it like:
Arude, Binaryh, Blancah, Clawz SG, Jobe, Kris Davis, Mashk, Nick Devon, Soul Button
Is that possible?
Thank you,
Gregory

Yes, because in

there is no comma.
it should be
`$loop(%artist%,1) %artist%, $loopend()`
I am not sure what the

is doing in that code as it concludes a

Please ignore the /span
I just follow your suggestion please see below:
```
$loop(%artist%,1) %artist%, $loopend()
$loop(%mixartist%,1) %mixartist%, $loopend()
```
Results:
ARTIST: Arude, Binaryh, Blancah, Clawz SG, Jobe, Kris Davis, Mashk, Nick Devon, Soul Button, Soul Button, Nick Devon,
REMIXERS: , A, B, C,
The issue:
On the last artist "Nick Devon" as it's last there not the comma should appear.
REMIXERS: starts with a comma and ends with a comma.
I wish to see the correct export configuration as below:
**ARTIST: Arude, Binaryh, Blancah, Clawz SG, Jobe, Kris Davis, Mashk, Nick Devon, Soul Button, Soul Button, Nick Devon**
**REMIXERS: A, B, C**
Many thanks for your time.

I know.
I do not think that it is possible with such a loop.
The comma in front of the mixartist suggests for me that you have a file without a mixartist. This file then sorts to be at the beginning of the list

I see, I thought it was easy with the loop settings. I hope in near future to be a solution on that.
Thank you very much for your time and help.

Inspired by [Detlev's work](https://community.mp3tag.de/t/listing-all-artists-from-album-into-one-tag-field/14438/10), it's possible to collect all artists in a variable:
```auto
$filename(txt,UTF-8)
$loop(%ALBUM%)$puts(ListOfArtists,)$loop(%ARTIST%)$loop(%ALBUM%)$puts(ListOfArtists,$get(ListOfArtists)%ARTIST%', ')$loopend()$loopend()
$loop(%ALBUM%)$puts(ListOfArtists,$trim($regexp($get(ListOfArtists),'(?:(?<=,)|(?<=\A)|(?<=^))\s?([^,]*),(?=.*?(?<=,)\s?\1(?=,|\Z|$))(?#remove dups from comma- or comma+space- delimited list)',),', '))$loopend()
$loop(%ALBUM%,1)%ALBUM%
$get(ListOfArtists)
$loopend()$loopend()
```
The same needs to be done for the `%MIXARTIST%` then. It's kinda magic — but fun 🤓

... and all this just to avoid the trailing comma ... oh, well.
On the other hand: it proves that there is almost always a solution.
Enjoy.

Hello guys, @Florian
This configuration does the magic trick. Work perfectly on both `%ARTIST% / %MIXARTIST%`
Many thanks for that.

Would anyone be able to help me? I'm tyring to get this export result:
work (artist, artist) etc. So far, I have this:
```auto
$filename(txt,utf-8)
$loop(%work%)%work% ($loop(%artist%,1)%artist%$if($next(%artist%),', ',))$loopend()
$loopend()
```
However, this results in this: Artist, ARtist, ).

Where did you get this syntax?

Esp. $next() seems to be a function that I cannot find in the documentation:

Chat GPT gave that to me.

I would ask Chat GPT what has to be modified as that code does not work.
```auto
$filename(txt,utf-8)
$loop(%work%)%work% ($loop(%artist%)%artist%, $loopend())
$loopend()
```
What about this code?

Well, this one repeats recurring artists and still ends with , ). ChatGPT is stuck, I asked it about ten times.
