What is CSV to JSON Converter?

CSV (Comma-Separated Values) is the standard tabular data format used by spreadsheets like Microsoft Excel and Google Sheets.

This tool parses CSV rows and columns into an array of structured JSON objects, automatically mapping the first row as object keys.

It supports custom delimiters (commas, semicolons, tabs), handles quoted text fields, and automatically parses numbers and booleans into native JSON types.

How to Use

  1. Paste or type your CSV data into the input box.
  2. The structured JSON array is generated automatically in real time.
  3. Click 'Copy' to copy the resulting JSON.
  4. Click 'Sample' to test with sample CSV rows.

FAQ

Does the converter handle commas inside quoted text?
Yes, standard RFC 4180 quotation rules are respected; commas inside quotes are preserved as literal text.
