Because CSV is a land full of arbitrary stuff :) RFC 4180 is not a standard, it is merely an informational RFC. Other RFCs in this category include these pearls: UTF-9 and UTF-18 Efficient Transformation Formats of Unicode https://tools.ietf.org/html/rfc4042 Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0) https://tools.ietf.org/html/rfc2324 Electricity over IP https://tools.ietf.org/html/rfc3251 I took another look at RFC 4180 and it's not clear to me how the empty lines are supposed to be handled, this case is not explicitly mentioned. Considering that it's better not to lose information when parsing I'm inclined to think that empty lines shouldn't be thrown out by default. Emmanuel Bourg
