What this tool does

JSON Tree Viewer displays valid JSON as an interactive hierarchy, so you can inspect nested objects, arrays, keys, and primitive values without uploading the document.

How to use

  1. Paste strict JSON into the editor.
  2. Select Build Tree.
  3. Expand objects and arrays, or search keys and values.
  4. Select a node to copy its value, JSON, or path.

Path formats

Dot paths are compact for ordinary keys, such as user.address.city. Keys containing spaces, dots, quotes, or numeric-looking names automatically use safe bracket syntax, such as ["contact.email"]. Bracket paths are also available for every selected node.

Privacy and limitations

Everything happens locally in your browser and input is not automatically saved. Only strict JSON is accepted. Very large trees can take longer to expand or search, and object key order is displayed as provided.

Frequently asked questions

Can I copy a JSON path?

Yes. Select any node and copy its dot path; the details panel also shows bracket notation.

Why are some paths shown with brackets?

Brackets safely represent keys that cannot be expressed reliably with dot notation.

Can the root be an array or primitive?

Yes. Arrays, strings, numbers, booleans, and null are all valid JSON roots.

Does the tree change the JSON?

No. The viewer only creates a local representation for display.

Can I search values as well as keys?

Yes. Search checks object keys, array indexes, strings, numbers, booleans, and null.

Why are comments rejected?

Comments are not part of the JSON standard, so the strict parser rejects them.

Practical guide

When to use it

Use it when a deeply nested response is hard to scan as text and you want to inspect one branch at a time.

Three steps

  1. Paste strict JSON and build the tree.
  2. Search for a key or value, then expand the matching branch.
  3. Copy the selected value, JSON fragment, or path for debugging.

Example and a common mistake

In an order response, expand customer → addresses → 0 instead of hunting through a long formatted document.

A tree is for inspection, not editing; copy a node before making changes elsewhere.
