Create JSON for Google auth credentials

[RUSA]

I am using Python to access a view in Google BigQuery (b/c the BQ connector can't access views). I need to create a JOSN so the code can read it as shown below:

os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "C:/Alteryx/Samples/GCP Big Query/xyz.json"

I have played with the JSON Build tool putting my credentials in txt and csv formats, but I can't come up with anything close to what is required.
