JSON is a very commonly used data format so you will come across it at some point.
In this video I show you how to get that data into houdini and manipulate your project geometry with it. In addition to this video there is an advanced version of this where I take a look at a more complex json file to extract its data and do funny stuff with it.
This is the basic video shared on youtube with its files going public after 4 days.
