I created List but the list is delimeted by "," and i want to convert it somehow to records(rows).
My goal is to have table with 2 columns: TableName, ColumnName for each table in folder.

 

Can you please help?
Best,
Jacek

Keep it as List only. I believe you created list by following formula in sample file

=Record.ToList(_)

After this, delete all columns from your sample file except last one.

Now, you will have this result in your combined file

When you click double arrow then, you get option for Expand to new rows and you will get following result
