All of these are good suggestions -- but when working with JSON I find this package to be very helpful:
https://github.com/hjson/hjson-go I use json as a config file for my programs and when users fat finger the config, forget a comma or put a space in the wrong place -- this for the most part fixes those minor blunders. I've also found that even though another system generated the JSON, it might not be fully compliant with what I wrote, hjson-go has bailed me out on more than one project.
