How do I get several items into one column, separated by commas?

Hey there I´m struggeling with this one.
I have 6 values in 1 row, I need to change the last one. So I used text split to extract and change it. That worked well. BUT now I need the 6 values to be in one column again, separated by commas and I don´t know how to do it.

Any ideas?

I guess you’re looking for textJoin.
