CSV stands for comma separated value, it is a type of file which allows data to be saved in a table structured format.
A CSV stores tabular data in plain text where each life of the file is a data record and each record consists of one or more fields, separated by commas.
Also recognised as a common data exchange that is widely supported by consumer, businesses, and scientific applications, a CSV is commonly used for moving tabular data between programs that natively operate on incompatible formats.
Although widely used in computers the CSV is a data format that pre-dates personal computers by more than a decade.
In 1972 the IBM Fortran compiler under OS/360 supported them.
Now commonly known as a specially formatted plain text file which stores spreadsheet or basic database-style information, they are sometimes also called comma delimited files.
Microsoft Excel is one of the most common examples of a program that uses CSV.
