How to iterate through an array/object input variable in JDE Orchestrator

I am very new to JDE Orchestrator, so this question is probably silly.

I receive a JSON array as an Input variable in JDE Orchestrator containing different data that I want to put into JDE by using JDE forms requests. So, how can I iterate over this array and execute a form request for each element in the array?

I have seen documentation on how to iterate over a dataset. Still, the information I want to iterate through is new (I am receiving it from an external service), so I can not get it from JDE as a dataset.

Can the array (or the object input variable) be converted into a dataset?
