JSON Tree Viewer Online

Explore nested JSON as an interactive tree

A long JSON response can be valid and still be difficult to inspect. The JSON Tree Viewer turns objects and arrays into expandable branches, so you can follow a value from the top level to the part you need. It is useful when checking an API response, tracing a configuration setting, or figuring out how an exported dataset is organized.

Paste JSON or open a local .json file, then select Load JSON. Expand only the branches you need, search keys or values, and select a node to copy its path. The viewer also reports how many objects and arrays the document contains and its maximum depth.

How to use the JSON Tree Viewer

1. Paste JSON in the input box, choose Open File, or use Sample JSON to see how the tree works.
2. Select Load JSON to parse the document and build the tree.
3. Expand a branch to inspect its children, or use Expand All and Collapse All to change the whole view.
4. Search for a property name or value. Use Prev and Next to move between matches.
5. Select a node and choose Copy Path to copy its location, or use Copy JSON to copy the parsed document.

Find where a value lives

A copied path starts at $, the root of the document. Object properties use dot notation when the key is a simple identifier, and array items use their zero-based index in brackets. For example, the status field in the first order of this response is at $.orders[0].status:

{
  "orders": [
    { "id": "A-104", "status": "shipped" },
    { "id": "A-105", "status": "processing" }
  ]
}

Copying the path is handy when you need to point a teammate to a field, document where a value appears, or use the location while debugging. The path describes where the selected node sits in this JSON tree; it does not change the data.

Use search and structure counts to narrow your view

Tree search checks property names and scalar values, including text, numbers, booleans, and null. Search is case-insensitive, highlights matching text, opens the branch containing a match, and lets you step through the results. For a response with many repeated records, searching a field such as email, an ID, or a status can be quicker than opening every array item.

Each object or array shows its number of keys or items. The summary above the tree counts objects and arrays and reports maximum depth. These counts help you spot the broad shape of a payload—for example, whether a response has a list of records or many nested configuration objects—but they do not validate the data against a schema.

Invalid JSON and values to double-check

The viewer must parse valid JSON before it can build a tree. If parsing fails, the error is shown and the text remains in the input so you can correct it. Common causes include a missing comma, a trailing comma, single-quoted strings, unescaped quotation marks, and unmatched braces or brackets. This tool reports syntax errors; it does not repair them. Use the JSON Validator to inspect syntax, or the JSON Repair Tool for help with common mistakes.

The viewer uses the browser’s JavaScript JSON parser. JavaScript cannot represent every very large integer or high-precision decimal exactly, so check long numeric IDs or precision-sensitive values before relying on the displayed or copied JSON. If exact digits matter, store them as quoted strings or use an arbitrary-precision JSON parser.

Does the viewer upload or edit my JSON?

The page reads pasted text or a selected file in your browser and parses it locally; the JSON input is not sent to a server by the viewer script. The tree is for inspection: it does not edit individual values. Copy JSON serializes the parsed data with indentation, so use the original input if you need to preserve its exact whitespace or source formatting.

This page is designed for exploring expandable branches, searching keys and values, checking structure counts, and copying a node’s path. If you want to switch between tree, code, and table presentations, open the JSON Viewer.
