What is a .CSV file?

CSV is a plain-text table format storing rows of comma-separated values. Opened in Excel, Google Sheets and any text editor.

Did you know
  • CSV has been used since the earliest days of computing but was only formally documented in 2005, as RFC 4180.
  • Despite the name, CSV files often use semicolons or tabs instead of commas, a habit that grew up in regions where the comma is the decimal separator.
  • Because there is no single authority over the format, quoting and line-ending conventions vary between tools, which is why a CSV exported by one program can confuse another.
  • A .CSV file is plain text, so you can open and edit it in any text editor.
  • On the web a .CSV file is served with the MIME type text/csv.
