RFC 7111 / CSV FRAGMENT GUIDE

Count rows and columns from one

Rows are records and columns are fields. Positions start at one, and a present header still occupies row 1.

RFC 7111 · § 2.1EXAMPLE

4 / 4

Count records, not line breaks

Separate CSV: a quoted two-line field remains part of one record; the next record is row 2.

A message needs an address.

Think of a packet as a small addressed envelope. Devices pass it onward; transport protocols decide what delivery promises an application gets.

These pictures are analogies to help you learn. The linked RFC explains the actual rules.

“Updates” changes part of an earlier RFC. “Obsoletes” replaces it. This list shows selected related documents.

KEY POINT

The RFC example counts its header as one of seven rows (§2); a header is not silently removed from the numbering.
row=4 identifies the fourth row; col=2 identifies the second column (§2.2).
Count parsed CSV records, not physical lines: a quoted field can contain a line break (RFC 4180 §2).
