JSON Tools

Format minified JSON, validate syntax, sort keys for stable diffs, escape strings for safe embedding, and convert between JSON and CSV. These browser-based tools help with API debugging, config files, and data imports — no signup required.

JSON Tools

• JSON Formatter

  Pretty-print minified JSON with readable indentation. Paste compressed JSON from logs or API responses and click Run to beautify it.

• JSON Stringify

  Minify formatted JSON into a compact single-line string. Paste indented JSON and click Run for API requests or environment variables.

• JSON Validator

  Check whether JSON is syntactically valid before deploying configs or debugging API responses. Paste your JSON and click Run to validate it.

• JSON Sort Keys

  Alphabetically sort object keys recursively for stable diffs, cleaner configs, and predictable test fixtures. Paste JSON and click Run.

• JSON Escape

  Escape quotes, newlines, and special characters so raw text can be embedded in JSON payloads or config files. Paste text and click Run.

• JSON Unescape

  Convert escaped JSON string values back to readable text. Paste an escaped JSON string (with or without surrounding quotes) and click Run.

• JSON to CSV

  Turn a JSON array of objects into CSV for spreadsheets and data imports. Paste JSON and click Run to generate comma-separated output.

• CSV to JSON

  Parse CSV with a header row into a JSON array of objects. Paste CSV data and click Run to produce formatted JSON.
