FAQ
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.
