Comma-separated values (CSV)

Comma-separated values (CSV) is a text format used to store tabular data in which values are separated by commas. It is typically used for transferring data between disparate applications, systems, and organizations as it can be used with many different operating systems and programs. CSV is a type of simple database format that stores tabular data in plain text, organized into lines where each line can represent a record, and the values separated by commas. Each line represents a row of data, and the columns of the data are indicated by the comma separators.

CSV files are plain text files that can be read and manipulated using any text editor or spreadsheet program. In a text editor, the file will typically be shown with the values separated by commas, hence the name comma-separated values. In a spreadsheet, the values will be displayed as a two-dimensional table, with the columns separated by commas. When a CSV file is imported into a spreadsheet, the data in the CSV file is typically organized into a worksheet with cell ranges for each column of data. The CSV file can then be manipulated and saved as an updated file.

Most spreadsheet programs allow users to import and export CSV files. CSV files are often used to transfer data between applications or systems that do not share the same database format. They are also used to share data sets with other programs, or to store data in a simple, easily readable format.

In addition to its use to transfer data, CSV is also used to store tabular data in text format. This is useful for sharing data or creating reports in a non-proprietary format. CSV files can also be used to store form data in web applications.

In modern web programming, CSV is used in conjunction with JavaScript-based applications to allow users to download data in CSV format. This helps to export data from web applications to existing applications or databases.

Thanks to its ease of use and flexibility, CSV is commonly used for data transfer, data storage, and data sharing.
