This RFC documents the format used for Comma-Separated Values (CSV) files and registers the associated MIME type "text/csv". This memo provides information for the Internet community.
I noticed a repository's .gitattributes entry for *.csv used text eol=crlf so I investigated and found this.
I think csv is a bad format, if you can even call it that. Yes, there are some cases where it makes sense. I worked with an oscilloscope at uni which output csv. But other than that, I consider it more of a concept than an interface / exchange standard
