Tabular data
Tabular data, organized as rows and columns, is often delimited. A field delimiter separates the columns of a row, with each column corresponding to a field in that row, and a record delimiter separates the rows, with each row corresponding to a record. The commonly used comma-separated values (CSV) format uses a comma to delimit fields, and an newline to delimit records. The following CSV data represents three records each with four fields. The first line is metadata that names the fields.
