What is CSV?

CSV, or Comma Separated Values, is a text file in which data is stored in a flat table structure. The values are separated from each other by a separator (e.g., comma).  
 

How does it work?
A CSV file contains only plain text, with the values within a row separated by a delimiter. The information is usually displayed as a table.
 

What are the advantages?
A CSV file allows data to be transferred between different systems. It can be read by almost any application.
