> When there are many and diverse data formats that meet that standard, it seems perverse to use the word "easy" to talk about empirically discovering the quirks in various undocumented dialects and writing custom logic to accommodate them.

But the premise of CSV is so simple, that there are only four quirks to empirically discover: cell delimiter, row delimiter, quote, escaped-quote.

I think it's "easy" to peek at the file and say, "Oh, they use semicolon cell delimiters."

And it's likewise "easy" to write the "custom logic", which is about as simple as parsing something directly from a text stream gets. I typically have to stop and think a minute about the quoting, but it's not that bad.

If a programmer is practiced at parsing from a text stream (a powerful, general skill that is worth exercising), than I think it is reasonable to think they might find parsing CSV by hand to be easier and quicker than parsing JSON (etc.) with a library.
