I’m joining two sheets with a match multiple relation and through a lookup I get the values into a new column, which then holds array values.
Unfortunately these array values can not be displayed in an inline list (e.g. in the details field).
Is there a way to convert this array into say a comma separated text field? Google sheet does not help as the lookup columns are not showing up in the sheet.
Thanks for your suggestions.
A Joined List column will do that for you.
Jeff, thank you for your tip,
unfortunately, when I try to create a new column (Joined List), the columns with the array values which I created first through the Relation or Lookup, don’t show up in the dropdown where you select the “Join the texts in:”, although they are in the same table where I want to create the new column.
Is there some other magic needed?
Are those single Relations? I mean, without Match multiple selected

No, Single Relations work, I have a true 1: n relation, see also in my title 
So you’re trying to join values in an array column?
Thank you, now it works with the joined list column.
Don’t know why it didn’t work in the first place.
I have 3 tables A, B, C and work with a m:1:n relation and obviously I mixed up some of the relations.
Now I get the values from A into C as a comma separated text value
