What is a CSV file?

CSV stands for Comma Separated Values. CSV files are plain text files separated by a comma and contain only numbers and letters. All the data present inside the CSV file is present in tabular or table form. Each line of the file is called a data record. Each record contains one or more fields which are plain text and separated by commas.

CSV is a common data exchange format that is used to exchange data usually when there is a large amount of data. Almost all the databases and consumer, business and scientific applications that store a large amount of information support this CSV format. Its best use among all the uses is moving data between programs in tabular form. For example: If any user wants to extract some data from database which is in proprietary format and want to send it to some other program which can accept a spreadsheet which uses a completely different format, then the database can export its data in CSV format which can be easily imported by the spreadsheet and can be used in the program wherever you want.
