What is a JSON formatter?

A JSON formatter is a tool that takes raw JSON data and formats it with proper indentation and line breaks, making it easier to read and understand. Our JSON formatter automatically adds 2-space indentation, organizes nested objects and arrays, and highlights syntax for better visibility.

How do I format JSON online?

To format JSON online: 1) Paste your JSON into the editor, 2) Click the "Format" button, 3) Your JSON will be instantly formatted with proper indentation. You can also use Ctrl+V to paste and the formatter will automatically beautify valid JSON.

Is this JSON formatter free to use?

Yes, jsonformatter.me is completely free to use with no limitations. There are no signup requirements, no ads, and no data limits. You can format, validate, and view as much JSON as you need.

Is my JSON data secure?

Yes, your JSON data is 100% secure. All processing happens directly in your browser - no data is ever sent to our servers. Your JSON never leaves your computer, making it safe for sensitive data.

What is the difference between JSON formatter and JSON viewer?

A JSON formatter beautifies JSON text with proper indentation, while a JSON viewer provides an interactive way to explore JSON data through tree views, graphs, or other visualizations. Our tool includes both - you can format JSON in the editor and explore it in the Tree View tab.

Can this tool fix invalid JSON?

Yes! Our JSON formatter includes an intelligent auto-fix feature that can correct common JSON errors like trailing commas, single quotes instead of double quotes, unquoted keys, and missing commas. It will show you what was fixed automatically.

Frequently Asked Questions

What is the difference between beautify and format?

In practice, "beautify" and "format" are used interchangeably for JSON. Both refer to adding indentation, line breaks, and proper spacing to make JSON human-readable. Our tool does both!

What indentation does the beautifier use?

Our beautifier uses 2-space indentation by default, which is the most common standard for JSON. This provides good readability while keeping files compact.

Can I beautify minified JSON?

Minified JSON (all on one line with no spaces) is exactly what this tool is designed for. Paste your minified JSON and click Format to expand it into readable, properly indented code.

Can I also minify/compact JSON?

Yes! Use the Compact button to do the reverse - remove all whitespace and create a single-line, minified version of your JSON. Great for reducing file size for production.
