How to convert CSV to JSON

  1. Paste your CSV text into the input box, or copy it straight from a spreadsheet.
  2. Choose the delimiter your file uses: comma, semicolon or tab.
  3. Decide whether the first row holds the column names.
  4. Click Convert to JSON, then copy the result or download it as a .json file.

FAQs

Can it handle commas inside quoted fields?

Yes. The converter uses a proper CSV parser, so commas, semicolons and newlines inside double-quoted fields are preserved correctly.

Do I need a header row?

No. If you uncheck the header option, the converter generates numeric keys like "column1", "column2" for each row.

Is my data sent to a server?

No. The whole conversion runs locally in your browser, so your spreadsheet data never leaves your device.

What does the downloaded file look like?

The .json download contains the same pretty-printed JSON array you see on screen, ready to use in applications and APIs.

Why convert CSV to JSON?

JSON is the native format for most APIs and web applications, so converting CSV exports lets you use spreadsheet data directly in code. The tool handles quoted fields with embedded commas and newlines.

Tips and Limits

All values are parsed as strings by default — numbers, booleans and dates are not type-converted. Everything runs locally, so your data never leaves the browser.
