CSV to JSON Converter

CSV to JSON Converter turns spreadsheet data — exported from Excel, Google Sheets, or a database — into a clean JSON array of objects that any application or API can consume directly. The first row is read as column headers, each subsequent row becomes one JSON object, and values are automatically typed as numbers, booleans, or strings based on their content.

The parser follows standard CSV escaping rules, so quoted fields containing commas, line breaks, or embedded quotes are handled correctly rather than breaking your columns apart.

• Header-row detection: The first row automatically becomes your JSON object keys.
• RFC 4180 parsing: Quoted fields with embedded commas, quotes, and line breaks are parsed correctly.
• Automatic type detection: Numbers, booleans, and null are converted to their real JSON types; everything else stays a string.
• Instant, in-browser conversion: No upload, no server round trip, no account.
• Copy or download: Grab the JSON directly or download it as a .json file.

1. Paste your CSV data into the input box, or click "Load Sample" to see an example.
2. Click Convert to generate the JSON output.
3. Review the array — each row becomes one object, keyed by the header row.
4. Copy the JSON or download it as a .json file for use in your app or API.

Example 1: A CSV exported from Google Sheets with name, email, and signup_date columns converts directly into a JSON array of user objects, ready to import into a database or send to an API.

Example 2: A product catalog CSV with a description field containing commas and line breaks converts correctly as long as that field is quoted in the CSV, keeping every column properly aligned.

• API-ready output: Turn a spreadsheet export into the JSON body your application or API expects.
• Correct type conversion: Numbers and booleans are detected automatically instead of staying as text.
• Handles messy real-world CSVs: Quoted commas and line breaks do not break your data structure.
• 100% private: Nothing is uploaded — conversion runs locally in your browser.
