What is CSV?

CSV is a plain-text format for tabular data where each line represents a row and commas separate column values. It is the most universal data-exchange format — virtually every database, spreadsheet application, CRM, and analytics tool can import and export CSV files without any special configuration.

Common uses for CSV

  • Exporting database records for analysis in Excel or Google Sheets
  • Importing contact lists, product catalogues, or financial records
  • Data exchange between different software systems and APIs
Note: CSV has no standard for data types, number formats, or multiple sheets — all values are stored as text. Commas inside values require careful quoting.

Compatibility: Universal — supported by Excel, Google Sheets, LibreOffice, every database system, and virtually all data tools.
