How is this different from the JSON Formatter?

The formatter prettifies/minifies JSON text. The viewer renders it as a visual tree with syntax highlighting, collapsible nodes, and search.

Can I edit JSON in the viewer?

The viewer is read-only for safe exploration. Use the JSON Formatter to edit and reformat JSON text.

What's the maximum JSON size?

Handles typical JSON (up to a few MB). Very large files with thousands of nodes may slow the tree rendering.
