And the best thing about CSV is that it is a text file with a standardized, well known, universally shared encoding, so you don't have to guess it when opening a CSV file. Exactly in the same way as any other text file. The next best thing with CSV is that separators are also standardized and never positional, you never have to guess.

Technically there is a CSV standard in IETF RFC 4180, although compliance isn't required and of course many implementations are broken.

Almost missed the sarcasm :)
