How to use the JSON viewer

Paste JSON into the left editor. The tree renders automatically after 300ms, or instantly on paste.
Navigate the tree on the right. Click ▼ / ► on any object or array node to collapse or expand it.
Copy a JSONPath by clicking any leaf value — string, number, boolean, or null. The path (e.g. $.user.address.city) copies to your clipboard instantly.
Format your JSON with the Format button before exploring if it arrived minified or on a single line.
Use Expand All / Collapse All to bulk-navigate deep structures. Use Sample to load a built-in example and try the viewer immediately.

JSON editor online — editing directly in the viewer

Most JSON viewers are read-only. This tool combines a live JSON editor online with the tree — so you can edit raw JSON on the left and watch the tree update in real time. Common uses:

Fix syntax errors interactively — the status bar shows the exact line and column of any parse error
Add, remove, or rename keys and immediately see the structural impact in the tree
Test how a JSON payload looks before sending it to an API or writing it to a config file
Explore an API response by pasting it directly from your browser's Network tab

The editor debounces input at 300ms — you get a clean rendering experience without the tree flickering mid-keystroke. Hit Format to auto-indent if you are working with minified JSON.

JSON tree viewer — navigating nested structures

Flat text is hard to navigate once a JSON document exceeds a few dozen lines. The JSON tree viewer turns nested objects and arrays into an indented, collapsible hierarchy:

Objects show {n keys} when collapsed — you see the shape without opening every branch
Arrays show [n items] when collapsed — you see the count at a glance
Leaf values are colour-coded: strings green, numbers blue, booleans orange, null grey
The status bar shows total node count, max depth, byte size, and parse time

This is especially useful for API responses, configuration files, database exports, and any JSON that arrived minified or deeply nested.

JSON visualizer — understanding structure at a glance

A JSON visualizer makes the shape of your data visible without reading every value. The tree view here serves as a structural visualizer: collapse everything to depth 1 with Collapse All and you see all the top-level keys of your document. Expand one branch at a time to drill into the part you care about — no scrolling through hundreds of lines of text.

This approach scales to any document size. A graph-based visualizer works well for small, highly connected objects but becomes unreadable for API responses with 50+ keys. The tree stays navigable regardless.

JSON Crack alternative — how this compares

JSON Crack renders JSON as an interactive node graph — striking for small documents with clear entity relationships. This viewer takes a different approach built for practical, daily use:

Feature	Xerobit JSON Viewer	JSON Crack
Large JSON (>100 keys)	Fast — tree scales linearly	Graph gets crowded
Live editing	Yes — 300ms debounce	Limited in free tier
JSONPath copy	Click any value	Not available
No account required	Always free, no sign-up	Account for full features
Works offline	After first page load	No

Use a graph visualizer when you want to see how entities reference each other in a small document. Use this tree viewer when you need to navigate, edit, or extract paths from real-world JSON at any scale.

JSONPath — copy the exact path to any value

JSONPath is a query syntax for locating values inside a JSON document, analogous to XPath for XML. This viewer computes the full path to every node and copies it on click.

Path notation:

$ — the root document
$.key — an object property with a simple identifier key
$["key with spaces"] — a property with a complex or non-identifier key
$.array[0] — the first item of an array (zero-indexed)
$.user.address.city — a deeply nested path

Copied paths work directly with jsonpath-plus, Python's jsonpath-ng, and most JSONPath implementations. For jq, replace $. with ..

Frequently asked questions

Does this JSON viewer work offline?

Yes. Once the page has loaded, all processing runs in your browser via the native JSON.parse engine — no server is involved. Disconnect from the internet and the viewer, editor, and path-copy all keep working. Bookmark the page or use your browser's "install as app" option for one-click access.

What is the maximum JSON size this can handle?

The browser's JSON parser handles hundreds of megabytes without issue. The tree renderer may become slow above roughly 5,000 rendered nodes because the DOM must create that many elements. For typical API responses — up to a few thousand nodes — rendering is instant. For very large exports, collapse the top-level nodes first and expand only the sections you need.

What is the difference between this and the JSON Formatter?

The JSON Formatter is a text transformation tool — it takes raw or minified JSON and outputs prettily-indented text. This JSON Viewer renders the same data as a navigable tree and adds live editing. Use the formatter when you need clean indented text to paste somewhere; use the viewer when you want to explore or understand the structure.

Is my JSON sent to any server?

No. Every operation — parsing, tree rendering, JSONPath computation, clipboard copy — runs entirely in your browser. Open DevTools → Network tab, paste some JSON, and you will see zero requests generated. Sensitive payloads (auth tokens, API responses, personal data) are safe to paste here.
