(adj.) Comma-delimited is a type of data format in which each piece of data is separated by a comma. This is a popular format for transferring data from one application to another, because most database systems are able to import and export comma-delimited data.
For example, data pulled from a database and represented in comma-delimited format looks something like the following. Each column value is separated by a comma from the next column’s value and each row starts a new line:
Adams, Jane, 46, female, New York
Doe, John, 32, male, California
Jones, Sam, 13, male, Texas
Smith, Mary, 64, female, Louisiana
When data is represented in this format they also are referred to as comma-separated values (CSV).
