JSON Viewer

What is a JSON Tree Viewer?

A JSON tree viewer renders JSON as a collapsible, hierarchical structure — like the file tree in a code editor — making it dramatically easier to navigate deeply nested data. Instead of searching through thousands of lines of text, you can expand only the branches you care about.

This viewer uses virtualized rendering: only the nodes currently visible in the viewport are rendered in the DOM. This keeps it perfectly smooth with 100,000+ node JSON structures that would freeze a naive implementation.

How to use this JSON Viewer

1. Paste JSON into the input box, or drop a .json file.
2. The tree renders immediately — click the arrow icons to expand or collapse branches.
3. Use the Search bar to filter nodes by key name or value. Matching nodes are shown; non-matching branches are hidden.
4. Hover any node and click its path label (e.g. $.users[0].email) to copy the full JSONPath to your clipboard.

What is JSONPath?

JSONPath is a query language for JSON, similar to XPath for XML. A path like$.store.book[0].title navigates from the root ($) down through the object tree. JSONPath is supported by many languages and tools — you can use the copied path directly injsonpath-plus, Python's jsonpath-ng, or Java's Jayway JsonPath.

Why privacy matters when exploring JSON

API responses, database exports, and log files often contain PII, authentication tokens, and internal system details. This viewer runs entirely in your browser — no JSON is ever sent to a server, and there are no server logs. You can safely explore sensitive data structures without risk of exposure.
