JSON Tools

JSON Formatter

Paste JSON or upload a .json file, then format, minify or validate it. Errors include line and column numbers. Processing happens in your browser — your JSON is not stored.

Your JSON is processed securely in your browser and is not stored unnecessarily.

How it works

  1. Paste JSON, type in the editor, or upload a file.
  2. Run the tool. Processing stays in your browser whenever possible.
  3. Copy or download the result. Nothing is written to server storage.

FAQ

No. Formatting, minifying and validation run in your browser. JSON is not stored or logged.

JSON files up to 2 MB. Larger payloads should be pasted only if your browser can handle them.
