The problem is that i get 2 columns and one has a nested table inside and the other one just the value.

My output need to be something like this:

Can anybody help?

Try adding a new custom column like this:

= Table.AddColumn(PreviousStepNameHere, "FREQ Expanded",
      each if Value.Type([FREQ]) = Value.Type("text") then [FREQ]
           else Table.ToList([FREQ]))

And then expand that new column using this code:

= Table.TransformColumns(#"Added Custom", {"FREQ Expanded",
      each if Value.Type(_) = Value.Type("text") then _
           else Text.Combine(List.Transform(_, Text.From), ","), type text})

If your type for non-tables is something else, then adjust accordingly.
