Push reference data to client-side data

I wish to create a data lookup table and without using REST API since it is overkill and not free.

I have created a client-side data source with three fields (plus ID) and the subsequent data variable.

I envision creating a text variable and making the initial value a CSV string including the ID field and then (some function-ing) them into the data variable. There are 42 entries (168 elements).

Thank you for your thoughts, help and direction.

Hello, anyone out there from Appgyver?
