IWR1642: Create Chirp .cfg File

Part Number:IWR1642

I'm using the people counting demo with my IWR1642, and I want to load my own chirp configuration file onto the GUI. I have used the mmWaveSensing Estimator to figure out what my chirp parameters should be, but that saves the configuration into a .json file. How do I actually create the .cfg file that I can load into the people counting GUI?
