About this JSON formatter
JSON (JavaScript Object Notation) is a plain-text format used almost everywhere to store and move data between apps, websites and APIs. It is easy for machines to read but quickly becomes a tangled wall of text for people. This free JSON formatter fixes that: paste raw JSON and beautify it into clean, indented lines you can actually read and debug. If there is a syntax mistake — a missing comma or bracket — it tells you instead of failing silently. When you are ready to ship, the minify button strips every unnecessary space so the data travels as small as possible. Everything runs locally in your browser, so even sensitive data never leaves your device.
Frequently asked questions
- What does a JSON formatter do?
- It lays JSON out with neat indentation so it is easy to read, and points out errors that would break it.
- What does minify mean?
- It removes spaces and line breaks to make the JSON as small as possible — the opposite of beautifying.
- Is my data safe?
- Yes — all formatting happens in your browser. Nothing is uploaded.
