HEY @Patrick_Kelly
Welcome To the community
Here I am using a Parse JSON module to get te structure of your JSON
you will have It mapped from your module instead
Use an iterator and map the agreementNumbers Array to it
Next use a text aggregator Module turn on advance options use ,(comma as row separator)
and map the fields following way
Use a set variable and map the data from text aggregator here and make it an array
hope this helps
