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 a JSON viewer?

A JSON viewer is a tool that displays JSON data in an interactive, visual format instead of raw text. It typically shows data as a tree structure where you can expand and collapse nodes, making it easier to navigate complex nested data.

How is a JSON viewer different from a formatter?

A JSON formatter beautifies the text representation of JSON with indentation. A JSON viewer goes further by providing interactive visualization - tree views, graphs, and the ability to explore data by clicking rather than scrolling through text.

Can I edit JSON in the viewer?

Yes! Our tree view supports inline editing. Click on any value to modify it, and the changes will be reflected in the editor. This makes it easy to update specific values in large JSON documents.

What is the graph view for?

The graph view shows JSON data as a visual network diagram, making it easier to understand relationships between different parts of your data. It's especially useful for data with many cross-references or nested structures.
