What Is CSV?

CSV (Comma-Separated Values) is one of the most common data exchange formats. Each line represents a row, and values within a row are separated by commas (or another delimiter). The first line typically contains column headers. CSV is supported by virtually every spreadsheet application, database tool, and programming language.

CSV Parsing Rules

Fields containing commas, double quotes, or newlines must be enclosed in double quotes. A double quote inside a quoted field is escaped by doubling it (""). For example, the value He said "hello" becomes "He said ""hello""" in CSV. This tool handles these edge cases correctly according to RFC 4180.

Common Delimiters

• Comma (,) — Standard CSV format used by Excel, Google Sheets, and most tools
• Tab (\t) — TSV format, common in bioinformatics and database exports
• Semicolon (;) — Used as the default CSV delimiter in European locales where comma is the decimal separator
• Pipe (|) — Used in some database and mainframe data exports
