JSON Viewer

Explore a JSON document as a collapsible tree with paths you can copy.

Quick Tool Overview

The JSON Viewer turns a document into a collapsible tree. Every branch shows how many keys or items it holds, every leaf shows its value with the type colour-coded, and clicking any node copies its full dot-notation path.

What it does
Renders JSON as an expandable, searchable tree
You give it
Any valid JSON document
You get back
A navigable tree with copyable paths for every node

About the JSON Viewer

A large API response is unreadable as raw text and only slightly better pretty-printed. The viewer turns it into a tree you can walk: every object and array is a branch you can collapse, and every leaf shows its value with the type colour-coded.

The part that saves the most time is the path. Click any node and its full path is copied in dot notation — data.items[0].price — ready to paste into your code, a JSONPath expression or a test assertion. Branch headers show how many keys or items they hold, so you can see the shape of a thousand-item array without expanding it. There is also a filter box that hides everything except the branches matching your search.

Key features of the JSON Viewer

Copy the path to any node

One click puts data.items[0].price on your clipboard, ready for your code, a test assertion or a JSONPath expression.

Collapse what you are not reading

Branches fold away with their child count still visible, so a thousand-item array takes one line until you want it.

Filter to matching branches

Type in the filter box to hide everything except the nodes whose key or value matches your search.

Types at a glance

Strings, numbers, booleans and nulls are colour-coded, so a number that arrived as a string is obvious immediately.

Expand and collapse everything

Two buttons open or close the whole tree, which is the fastest way to get a feel for an unfamiliar payload.

How to use the JSON Viewer

  1. 1

    Paste your JSON

    Any valid document, from a two-key object to a deeply nested API response.

  2. 2

    Expand and collapse

    Click a branch to open or close it, or use the buttons to expand and collapse everything at once.

  3. 3

    Filter to what matters

    Type in the filter box to show only the nodes whose key or value matches.

  4. 4

    Copy a path

    Click the path chip beside any node to copy its full dot-notation path to the clipboard.

Frequently asked questions

Documents of a few megabytes render fine. Very large arrays are collapsed by default so the page stays responsive, and you expand only the branches you need.
