How to use JSON Viewer
- 1
Paste your JSON
Paste a JSON document into the input area. The tree view appears on the right.
- 2
Expand and collapse
Click any object or array node to expand or collapse it. The first two levels are expanded by default.

Search and copy
Filter nodes by key or value with the search input. Hover any node to see its JSON pointer path; click Copy to put a subtree on the clipboard.
Frequently asked questions
- Does this tool upload my JSON?
- No. Every parse, transform, and download runs entirely in your browser using JavaScript and Web Workers. The file never leaves your device — there is no upload endpoint and no server-side processing.
- What's a JSON pointer?
- A JSON pointer (RFC 6901) is a slash-delimited path that addresses a value inside a JSON document, like /users/0/email. The viewer shows the pointer for the node you hover.
- Can I edit the JSON in the tree?
- No — the tree view is read-only. To modify JSON, use JSON Formatter or paste into JSON to TypeScript / JSON Path Evaluator for transformations.
