CSV#
A plain-text format that use newlines to delineate rows and a user-specified delimiter (usually a comma) to separate the values of each column in a data table. Comma-Separated Values (CSV) format is a common format but suffers from not being able to retain type information - thus, all data is imported as categorical data (strings) by default.
Note
This implementation of CSV is based on the definition in RFC 4180.
Interfaces: Extractor, Writable
