🌳 JSON Tree Explorer
Interactive JSON tree explorer for inspecting large payloads — collapse branches, search nodes, copy JSONPath. A focused tree-first inspection tool, distinct from a full JSON formatter/validator.
About this tool
This tool renders JSON as an interactive tree where you can collapse and expand nested objects and arrays — focused purely on inspection and navigation, without the formatting, validation, and minification features found in the full JSON Formatter. It is built for exploring large payloads where structure matters more than syntax.
Click any node to copy its JSONPath (e.g. $['users'][0]['name']), search for keys or values with keyboard navigation, and see stats like total key count and maximum nesting depth at a glance — details not available in a general-purpose formatter.
It's useful when debugging API responses, exploring configuration files, or understanding deeply nested data structures. The tree view makes it easy to find specific values — collapse everything except the branch you care about, then search within it.
Example: paste a 10,000-line API response, collapse most nodes, and search for email to jump straight to all email addresses in the payload. Click on one to get its JSONPath, which you can use to reference it in code.
FAQ
Does this tool upload my JSON? ›
No. Everything runs in your browser — the JSON stays on your device. The tree is rendered locally using the DOM, with no network requests.
What is JSONPath? ›
JSONPath is a query language for JSON, similar to XPath for XML. Paths like <code>$["users"][0]["name"]</code> refer to specific values in a JSON document. Clicking any tree node copies its JSONPath so you can paste it into your code.
Is there a size limit? ›
The practical limit depends on your browser and machine. Large JSON files (50MB+) may cause performance issues. For very large files, consider using <code>jq</code> or a dedicated JSON editor.
How is this different from the JSON Formatter? ›
The <a href="/json-formatter" class="text-accent hover:underline">JSON Formatter</a> is a full beautifier, validator, and minifier with JSONC support — its built-in tree is a secondary feature. This Tree Explorer is a focused tool for navigation: you paste JSON, collapse and expand branches, search nodes, and copy JSONPaths. No formatting UI, no minification, no sharing links — just inspection.
