Free JSON Tree Viewer with Search
Paste any JSON and explore it as a collapsible tree, then search for a specific key or value to find it instantly — matching branches expand automatically so you never have to hunt through a large payload by hand.
How to Use It
Paste your JSON into the left panel. Type into the search box above the tree to filter for a key name or value — every node containing a match is expanded automatically and the matching text is highlighted, so you can jump straight to what you're looking for in a large or deeply nested document.
Example
In a large API response, searching for email highlights every key named "email" anywhere in the tree and auto-expands each of their parent objects, even if they were originally collapsed several levels deep.
Common Use Cases
- Finding a specific field buried inside a large, deeply nested API response.
- Checking whether a particular key or value exists anywhere in a config file.
- Auditing a JSON payload for a specific ID, email, or status value during debugging.
FAQs
How is this different from the plain JSON Viewer?
The JSON Viewer is a general-purpose collapsible tree explorer. This tool adds a search box on top of that same tree so you can filter for a specific key or value by typing — matching branches auto-expand and matches are highlighted, which the plain viewer doesn't do.
Is the search case-sensitive?
No — the search matches keys and values as a case-insensitive substring, so searching "email" also finds "Email" or "EMAIL".
Is my JSON data uploaded anywhere?
No — parsing, searching, and rendering all happen entirely client-side in your browser. Your data is never sent to a server.
