What is a JSON Viewer?

A JSON viewer turns raw JSON into an expandable tree so nested objects, arrays, keys, and values can be inspected without scanning a long text file. It is especially useful for API responses, logs, configuration snapshots, analytics events, and documents where the field you need may be several levels deep.

JSONFather combines tree navigation with search, path copying, value copying, JSON Pointer output, and a table preview for arrays of objects. The document is parsed and explored in your browser, so debugging private API payloads does not require uploading data to a remote viewer.

How to View JSON as a Tree

Paste JSON into the editor and choose View JSON. Expand only the branches you need, search by key or value, and copy the JSONPath or JSON Pointer for fields that need to move into code, documentation, alerts, or bug reports.

FAQ

Can I inspect nested arrays?

Yes. Expand arrays and objects, search across paths and values, and copy the exact location you need.

What is copied for a tree node?

You can copy the node value, its display JSONPath, or its JSON Pointer path.

Does the viewer work offline?

After the page loads, parsing and tree rendering happen in the browser without a server round trip.
