[Plugin] Http/s REST, blueprintable JSON query and Parse API manager [VaRest]

I’ve toyed with this plugin before, but when I first looked I was a bit more noob. I’ve been reading that google sheets supports JSON - could anyone show me a quick tutorial of how i’d set that up here? In the docs from google it shows you how to pull stuff with python or with jquery but is there an easy way to access the data with this plugin?

Thanks!
