Hello all, I apologize in advance, my request is so simple that it is probably already answered somewhere, but I really couldn't find it.
In my %artist%, I have: Ancerl, Karl
I would like to capitalize only the first word (the surname) to arrive at: ANCERL, Karl
How do I achieve this?
Thank you in advance!

Try an action of the type "Format value" for ARTIST
Format string: `$upper($regexp(%artist%,'(.*), (.*)',$1)), $regexp(%artist%,'(.*), (.*)',$2)`
