XLS Writer for sets

Dear all,

I want to extract my list of sets data into xls file.
The problem is that it is not possible to do this directly so I splited the sets and combined them all.
The new problem here is that because I have different amout of values
I get some V1,v2,?,?,?,?,?,? and so on
How can I get just the values without non desired commas
How to solve this problem better ?
thanks in advance

string manipulation node before excel export with the expression :

replace($combined string$, “,?”,"")

should do the trick.
