Yep, healthcare, grocery, logistics, data science. Heck it would be easier to list industries that DON'T have any CSV. There aren't many.

In terms of interchange formats these are quite popular/common: EDI (serialized as text or binary), CSV, XML, ASN.1, and JSON are extremely popular.

I 100% assure everyone reading that their personal information was transmitted as CSV at least once in the last week; but once is a very low estimate.
