 CSV is not a file format, it is typically a loose set of guidelines of how to
 structure tabular data into a plain text string. As such there's an endless
 amount of `*.csv` files floating around which are highly incompatible with

 ## Terminology
 
 - **Field** — A singular String value within a row.
-- **Row** (or **Record**) — A collection of fields.
+- **Record** (or **Row**) — A collection of fields.
 - **Column** — Fields from multiple rows at the same offset. For example the
   second column would be a list of the second field from every row.
 - **Delimiter** — The character used to separate fields withing a
   row. Commonly this will be a comma (`,`), but semi-colons (`;`) or tabs
   (`\t`) are two other popular delimiter characters.
 - **Header** — The first row is often used to contain the column names for all
-  remaining rows. Header names would be used as key names during when CSV data
