TSV to JSON Converter

TSV to JSON Converter turns tab-separated data — exported from a spreadsheet, database, or command-line tool — 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.

Because TSV uses tabs rather than commas as its delimiter, it is a common choice for data that may already contain commas in the values themselves, and this converter handles both quoted and unquoted fields correctly.

• Header-row detection: The first row automatically becomes your JSON object keys.
• Quoted field support: Fields with embedded tabs, quotes, or line breaks parse correctly when wrapped in double quotes.
• 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 TSV 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: Data copied from a spreadsheet range with name, email, and signup_date columns pastes as tab-separated text and converts directly into a JSON array of user objects.

Example 2: A bioinformatics export with a description field containing commas converts cleanly to JSON, since commas do not interfere with the tab-delimited structure.

• API-ready output: Turn tab-separated data into the JSON body your application or API expects.
• Correct type conversion: Numbers and booleans are detected automatically instead of staying as text.
• Spreadsheet paste-friendly: Works directly with data copied from Excel or Google Sheets.
• 100% private: Nothing is uploaded — conversion runs locally in your browser.
