What is a JSON Formatter?

A JSON Formatter (or beautifier) is a tool that takes raw, minified, or disorganized JSON data and formats it with proper indentation, making it easier for humans to read and understand.

How do I format JSON?

Simply paste your raw JSON string into the input area and click 'Format JSON'. If your JSON is valid, it will be instantly prettified.

Is my JSON data safe?

Yes, all parsing and formatting operations are performed locally in your browser. We do not store or send your data anywhere.
