What is CSV to JSON?

CSV to JSON parses comma-separated values and produces a JSON array. When the first row is a header, each value becomes a named field, which makes the output easy to use in code and APIs.

How to use this tool

  1. Paste your CSV into the input box.
  2. Choose whether the first row contains headers.
  3. Click Convert to JSON.
  4. Copy or download the JSON result.

Features

  • Convert CSV to a JSON array
  • Choose whether the first row is a header
  • Pretty-printed JSON output
  • Copy the JSON output
  • Download the result as a .json file

This tool runs in your browser. Your files and text are not uploaded to our servers, and we do not store your input.

Frequently asked questions

What if my CSV has no header row?+

Turn off the header option and each row becomes an array of values instead of a named object.

Does it handle quoted values and commas?+

Yes. The parser understands quoted fields, so commas inside quotes are kept as part of the value.

Is my CSV sent to a server?+

No. Parsing happens entirely in your browser.
