JSON Viewer

Explore JSON data in an interactive collapsible tree view

What is JSON Viewer?

The JSON Viewer is a free online tool that renders JSON data as an interactive, collapsible tree structure, making it easy to explore deeply nested objects and arrays. Unlike a plain formatter, the viewer lets you expand and collapse nodes, search for keys, and navigate large JSON responses without scrolling through hundreds of lines.

Frequently Asked Questions

How is this different from JSON Formatter?

JSON Formatter outputs indented text. JSON Viewer renders an interactive collapsible tree for easier navigation.

Can I edit JSON in the viewer?

The viewer is read-only. Use the JSON Formatter to edit and format JSON.

Does it handle large JSON files?

Yes, but very large files over 5MB may slow down rendering. Works best with files under 1MB.

Can I search within the JSON?

Yes, use the search feature to find specific keys or values within the tree.

Is my data secure?

Yes, all processing happens locally in your browser. Your JSON data never leaves your device.
