It’s all bastard CSV out here in the real world.
For extra fun consider the German-Speaking word where CSV files are actually Semicolon-Separated but everyone still calls them CSV and looks at you like you drooled on yourself when you point out that “;” is not a “,”.
This appears to be because we use “,” as decimal separator and were too dense to learn how to use " properly in CSV.
Bastard CSVs as far as the eye can see.
