Unfortunately, JSON is much more annoying to edit.
Best way is to stop using both, and generate the objects from higher level language, at least something like Jsonnet (which is really just a step up, so better not stop there but I will take what I can)
I'm on the fence about this, something like Dahl seems good, but I am not a fan of using fully-fledged higher level languages (the Pulumi approach) as I've been burnt before with devs writing bad code and generating configs in the most confusing, convoluted way possible.
