Tools / JSON Viewer

JSON Viewer

Paste or drop JSON to explore it as an interactive tree. Expand and collapse nodes, search by key or value, hover for JSON pointer paths, and copy any subtree to clipboard.

Runs entirely in your browser

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.

  3. 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.
JSON Formatter

Format, minify, or validate JSON with configurable indentation and error reporting.

JSON Path Evaluator

Query JSON with JSONPath expressions and see matched values instantly.

JSON Diff

Compare two JSON documents side by side with structural diff highlighting.
