@whotwagner Can you please confirm if this is what you wanted? OR should every value end up as a variable, i.e.

"COMPANY_EMPLOYEES_0_PROJECTS_0": "App1"
instead of
"COMPANY_EMPLOYEES_0_PROJECTS": ["App1", "App2"],

I think that we go with: lists at the end instead of creating string-variables for every item.
