> If somebody give you a JSON file that isn't valid JSON, you tell them it isn't valid, and they say "oh, sorry" and give you a new one. That's the standard for "easy."

But it isn't that reliably easy with JSON. Sometimes I have clients give me data that I just have to work with, as-is. Maybe it was invalid JSON spat out by some programmer or tool long ago. Maybe it's just from a different department than my contact, which might delay things for days before the bureaucracy gets me a (hopefully) valid JSON.

I consider CSV's level of "easy" more reliable.

And even valid JSON can be less easy. I've had experiences where writing the high-level parsing for some JSON file, in terms of a JSON library, was less easy and more time-consuming than writing a custom CSV parser.

Subjectively, I think programming a CSV parser from basic programming primitives is just more fun and appealing than programming in terms of a JSON library or XML library. And I find the CSV code is often simpler and quicker to write.
