Yea and it's still a partially-parseable shit show with guessed values. But we can and could have and should have done better by simply defining a format to use.

I went looking at some of the more niche languages like Prolog, COBOL, RPG, APL, Eiffel, Maple, MATLAB, tcl, and a few others. All of these and more had JSON libraries (most had one baked into the standard library).

The exceptions I found (though I didn't look too far) were: Bash (use jq with it), J (an APL variant), Scratch (not exposed to users, but scratch code itself is encoded in JSON), and Forth (I could find implementations, but it's very hard to pin down forth dialects).

People keep saying this but RFC 4180 exists.

Even better, the majority of the time I write/read CSV these days I don't need to use a library or tools at all. It'd be overkill. CSV libraries are best saved for when you're dealing with random CSV files (especially from multiple sources) since the library will handle the minor differences/issues that can pop up in the wild.
