Group related fields together

Hey guys,

my biggest problem is that I dont know how to discribe what I want... otherwise I could goolge it easily...
I got a list with 100+ names and cities and i want to collect who is living in the same city.

Here an example:

Name City living in the same City
Hans München
Peter Berlin Stefan,Michael
Ben Hamburg Nadine
Nadine Hamburg Ben
Stefan Berlin Peter,Michael
Michael Berlin Stefan,Peter

Hans is the only one coming from München so the field is blank because I dont want to list its own name.
Peter is living in Berlin as well as Stefan and Michael. Therefore it says "Stefan,Michael".

Is there a function to do the third column? Important is that the names are seperated with a comma.

Thanks in advance!

Hi,
please upload your sample clause in excel, it's hard to tell how your columns are divided.

See the yellow banner at the top of the page for more instructions.

Hey Belinda200,

thanks for your fast reply. Please find attached my sample.xlsx.

Best regards

Being on version 2022 I assume you have access to the FILTER formula. If so, in C2 try this:

=TEXTJOIN(", ",TRUE,TRANSPOSE(FILTER($A$2:$A$7,($B$2:$B$7=B2)*($A$2:$A$7<>A2),"")))

and copy down.

ty for your help!
I tryed your function but I get some errors (maybe because I got an german excel verstion) so I had to adjust it a little bit:
=TEXTKETTE(", ";WAHR;MTRANS(FILTER($A$2:$A$7;($B$2:$B$7=B2)*($A$2:$A$7<>A2);"")))

Basically it works, but there is only a comma at the beginning of the cell and the word "true". Can this still be adjusted?

Thanks!

When I open your file, it has the CONCAT. Your version (if you're on Version 2022) you should have the TEXTJOIN formula available - it came out in V2019. I've attached the file. See if it works for you when you open it.

Gregb11: tyvm! You saved me a lot of time!

AliGW: You are right, I corrected it to Office 2021.

Thanks
