How To Access Each Value in column with a LIST datatype

I'm executing a google OSM call to for address validation.  When I use the JSON PATH node to collect the elements of the adress, I have a column with the LIST datatype.  Example [street,city,state,zip].  I need to loop through all the elements of that list column to perform operations.  I could convert it to  a string and then use the CELL SPLITTER node.  However I will never be certain how many elements are in the list.

 

Is there a node to loop through a LIST datatype column?  My only other alternative is to split the colum on the comma and then loop through all the potential columns generated.  A bit of a pain to code around.

How about ungrouping the column with the List cell? 

Than you can afterwards do the looping.
