What is a JSON viewer?

A JSON viewer renders JSON as an interactive tree. Objects and arrays can be collapsed, so you can navigate large documents without scrolling through thousands of lines.

FAQ

Does the viewer modify my JSON?

No. It parses the input and renders it for display only.

Can I copy part of the tree?

Yes. The output panel shows the formatted JSON. Use the Copy button to grab it.

Is my JSON sent anywhere?

No. Everything runs in your browser.
