This is nice, but trivial to accomplish with the “faker” library available for most major programming languages - almost all reasonable web test frameworks will allow you to just make this json locally with the generated values, often with almost the exact same/extremely similar template syntax shown here.

There’s also json-schema-faker which is pretty cool.
