JSON Tree Viewer, Explore & Navigate JSON Online
Paste or drop a JSON file and browse it as a collapsible tree. Instant key/value search with next-prev jumping, type and length badges on every node, and one-click copy of any value or its JSONPath. Nothing is uploaded.
What is the json tree viewer?
The JSON Tree Viewer renders JSON as an interactive, collapsible tree with type and array-length badges on every node. Expand or collapse branches, search keys and values with live highlighting and next/prev jumping, and copy any value or its JSONPath in one click. Free and fully in-browser. Nothing is uploaded.
A raw JSON response can be thousands of lines of nested objects and arrays, perfectly valid, and almost impossible to read as flat text. The JSON Tree Viewer turns that wall of braces into a navigable outline: each object and array becomes a collapsible node you can open only where you need it, so a 5,000-line API payload starts as a single tidy summary and expands on demand. Every node is annotated with its value type and, for arrays and objects, how many items it holds, so you can gauge the shape of unfamiliar data before drilling in. A live search box matches both keys and values as you type, highlights every hit, and lets you jump between matches with the keyboard: invaluable when you're hunting for one field buried deep in a huge document. Click any leaf to copy its exact value, or copy the fully-qualified JSONPath (like $.data.items[3].id) to paste straight into code, a jq filter, or a bug report. Large documents stay smooth because collapsed branches don't render their children until you open them. Everything runs locally in your browser, the JSON you paste never touches a server, so it's safe for real, sensitive payloads.

How to use the json tree viewer
- 1
Add your JSON
Paste JSON into the input, drag a .json file onto the pane, or load the built-in sample. It's parsed and rendered as a tree the moment it's valid.
- 2
Expand and explore
Click a node's caret to open just that branch, or use Expand all / Collapse all to reveal or fold the entire document. Type and length badges show what each node holds.
- 3
Search for what matters
Type a key or value into the search box. Every match is highlighted and the tree opens to show it. Press Enter or use the arrows to jump to the next and previous hits.
- 4
Copy a value or its path
Click any node to copy its value, or use the path button to copy the node's JSONPath. Both land on your clipboard ready to paste into code or a message.
- 5
Share your view
Use the share button to generate a link that reopens the exact JSON you're inspecting: the data travels in the URL fragment and still never touches a server.
What JSON Tree Viewer includes
Collapsible, drill-down tree
Objects and arrays render as expandable branches so a huge payload starts collapsed and clean. Open only the nodes you care about, or expand and collapse the whole tree with a single button.
Instant key + value search
Type in the search box and every matching key and value lights up as you go. Jump between hits with next/previous, and the tree auto-expands to reveal each match wherever it's buried.
Type & length badges
Each node is labelled with its type (string, number, boolean, null, object or array) and objects and arrays show their child count, so you can read the shape of the data at a glance.
One-click JSONPath copy
Click any node to copy its exact value, or copy its canonical JSONPath (e.g. $.items[2].name) ready to drop into code, a jq query, or a ticket. No more hand-counting nested brackets.
Handles large documents
Collapsed branches skip rendering their children until you open them, so multi-megabyte JSON stays responsive instead of freezing the tab like a naive pretty-printer would.
Entirely in your browser
Parsing, searching and path extraction all happen client-side. Your JSON is never uploaded, stored or logged, safe to explore production data, tokens, and other sensitive payloads.
Why use our json tree viewer
Understand unfamiliar APIs fast
See the structure of a response you've never seen before in seconds (which fields exist, how deep it nests, and how many items each array holds) without scrolling a flat text dump.
Grab the exact path you need
Stop mis-counting brackets. Copy a precise JSONPath for any value and paste it straight into your accessor code, a jq filter, or a test assertion, exactly as it appears in the tree.
Find one field in a haystack
When a document has hundreds of keys, live search with next/previous jumping takes you to the value you want immediately instead of Ctrl-F-ing through pretty-printed text.
Safe for real payloads
Because nothing leaves your browser, you can inspect live production responses, config blobs, and other sensitive JSON that you'd never paste into a tool that phones home.
Built for the way you work
From quick one-off fixes to daily workflows, see how people put this tool to use.
- API & backend developers
Inspect API responses
Drop a raw endpoint response in and read its shape as a tree, confirm a nested field exists, check an array's length, and copy the JSONPath to wire it into your parsing code.
- Frontend & mobile engineers
Trace data into the UI
Follow exactly where a value lives in a deeply nested payload before you write the selector, and copy the path so your component reads the right key the first time.
- QA & data testers
Verify payload structure
Search for a field to confirm it's present and correctly typed, spot an unexpected null, and capture the precise JSONPath for a reproducible assertion or bug report.
- DevOps & config wranglers
Read big config blobs
Open a sprawling config or Terraform state export as a collapsible outline, collapse the noise, and drill straight into the one section you need without losing your place.
Supported formats

Common problems, solved
Hit a snag? Here are quick fixes for the issues people run into most.
The tree won't render and shows a parse error.
Your input isn't valid JSON. Check for trailing commas, single quotes, unquoted keys, or comments: all illegal in strict JSON. The error banner points to the line and column. Fix that spot, or run the text through a JSON formatter first.
Search finds nothing even though the word is visible.
Search is case-insensitive but literal. Make sure you're not including surrounding quotes or brackets from the pretty-printed view. Try a shorter, distinctive fragment of the key or value you're looking for.
A very large file feels sluggish.
Collapse branches you're finished with and avoid Expand all on multi-megabyte documents. Because children render lazily, keeping most of the tree collapsed and using search to jump around stays fast.
The copied JSONPath doesn't work in my library.
JSONPath dialects vary slightly. This tool emits the common dot/bracket form ($.a.b[0]). Some libraries expect bracket-only ($['a']['b'][0]) or a different root token. Adjust the root or bracket style to match your query engine.
Get the most out of it
Collapse all first, then expand only the branch you're investigating, it's the fastest way to get your bearings in an unfamiliar payload.
Search matches values too, not just keys, so you can find every place a specific id or status string appears across the whole document.
Copy a node's JSONPath and paste it straight into a jq filter or your language's accessor to read the same value programmatically.
Use the share link to hand a teammate the exact JSON you're looking at. It rides in the URL fragment, so the data still never hits a server.
If a file is huge, keep sections collapsed and rely on search rather than expanding everything at once, which keeps the tree snappy.

Common tasks
Your privacy is built in
Your JSON is parsed, searched, and explored entirely inside your browser tab using JavaScript. Nothing is uploaded, stored, or logged on our servers. That local-only design is exactly why it's safe to inspect real production responses, configuration files, tokens, and other sensitive payloads here. When you share a view, the JSON travels in the URL fragment, which browsers never send to a server. Still, treat any link you create as containing the data itself and share it only with people you trust.
