JSON Formatter & Beautifier
Paste compact or hard-to-read JSON and format it with consistent indentation before sharing it, reviewing an API response, or committing a fixture.
- Choose two spaces, four spaces, or tabs to match your project.
- Invalid JSON is reported instead of silently changed.
- Copy or download the formatted result when you are finished.
This tool runs entirely in your browser. Your JSON is not uploaded, stored, or logged.
