Google API – JSON Help

I am using a Google API and getting JSON responses fine. I however cannot get the JSON to convert to anything useful. Convertfrom-json seems to produce system objects and useless garbage. I understand this might mean it doesn’t like the json format however I don’t know how to make this data useful/parsable. Here is a link to the json the API returns: https://drive.google.com/open?id=0B0FpxiKMv7vseXBsblhZbW9BX1U
