Adrian beat me to answering so I'll just add that different systems
generate and require slightly different CSV formats and though RFC4180
attempts to offer guidance, even that document states:

Definition of the CSV Format:

While there are various specifications and implementations for the CSV
format...there is no formal specification in existence, which allows for
a wide variety of interpretations of CSV files.
