A comma-separated values (CSV) file is used for the digital storage of data structured in a table of lists form, where each associated item (member) in a group is in association with others also separated by the commas of its set. Each line in the CSV file corresponds to a row in the table. Within a line, fields are separated by commas, each field belonging to one table column. Since it is a common and simple file format, CSV files are often used for moving tabular data between two different computer programs, for example between a database program and a spreadsheet program.
Most SIS, ERP, and HR systems can export and import data in CSV format, and the ability to automate the processing of CSV files is widely distributed, making it often the simplest way of moving data between systems.
