There exists a peculiar amnesia in software engineering regarding XML. Mention it in most circles and you will receive knowing smiles, dismissive waves, the sort of patronizing acknowledgment reserved for technologies deemed passé. “Oh, XML,” they say, as if the very syllables carry the weight of obsolescence. “We use JSON now. Much cleaner.”


Compression adds another layer of complexity for parsing.
JSON can also have configuration mismatch problems. Main one that comes to mind is case (in)sensitivity for keys.
Nahh your nitpicking there, large csvs are gonna be compressed anyways
In practice I’ve never met a Json I cant parse, every second csv is unparseable
