Entries of a repeating group to database

Hi,
I think I am having the same problem that @sharonherzog mentions here.
I able to successfully display the results from an API call (“entity extraction from text”) in a Repeating Group.
However, when I want to store the results in the database (as I want to filter, sort, manipulate the values) I can only store the results as LISTS. I cannot store each “cell” from the repeating group as a separate data entry.

I created this public demo app here so that you can see what I am trying to do:
API results in database

@georgeciobanu do you have any suggestions on how to approach this?

Thank you anyone and all for your help!

P.S.
I wasn’t able to create the demo in the forum app as it wasn’t allowing me to install the blockspring API. Different problem…another time.
