Streaming Dataset from a JSON API

Hi everyone,

So we are pulling data from a websource using a JSON API. However, the data that we get from the JSON API is not laid out in a flat file-like structure but has columns that look like the one below:

So basically, I have to transform the data first to get it to something more usable. My question is, the PBI streaming dataset looks like it requires to have your file in a flat file-like structure. Since my data isn't flat file-like in the first place, how can I achieve a streaming dataset with my data?
