Import JSON with mixed bag (Record, List, Scalar) in columns

[gxharr2]

I am importing JSON files into PowerBI. There are two columns in the data that can be a Scalar, a Record, or a List. I am a newer PowerBI user, and probably don't understand all I know about the tool. I have read the thread at Transforming json with power query (mix of list and record in a single column), and am still confused on how it all works.

Here is a sample image of the data after import:

After expanding CVEs, manually separating the Records from the List in PrevCVEs, and expanding that list, I'm left with:

in one of the columns. I have other JSON imports that will give a column with a mix of List, Record and Scalar values. I am trying to understand how to separate all these so that the import into PowerBI will work.

Here is a sample JSON:

I have come up with the solution, using M in Powerquery.  A combination of actions in the GUI and 'M' code written in Advanced Editor.
