Features

🌳

Collapsible Tree

Objects and arrays open as nested nodes. Open one branch at a time or expand everything with a single click.

🔎

Live Key Search

Filter by key or value as you type. Matches light up in yellow with a running count of hits.

📍

JSON Path Lookup

Click any node to see its exact path like $.items[0].id, ready to paste into code or queries.

🔒

Local Device Privacy

Parsing and rendering run in page memory only. Payloads never leave your device.

How to Use the JSON Viewer

  1. Paste raw or minified JSON into the Input JSON box, or click Load Sample.
  2. Click View JSON. Invalid input shows the exact line and column to fix.
  3. Open and close branches in the dark tree panel. Use Expand all or Collapse all for large files.
  4. Type in Search keys / values to highlight matches and jump to the right branch.
  5. Click any key or value to reveal its JSON path, then Copy Text or Download JSON to export.

Reading Nested JSON Without Getting Lost

API responses often arrive as one compressed line with hundreds of nested keys. The tree turns that line into indented levels: each object shows its key count, each array shows its length, and primitives carry a color by type — green strings, yellow numbers, pink booleans, gray nulls.

When the tree beats plain text

Use the tree when you need to inspect one branch of a 2 MB payload, compare two sibling objects, or find where an optional field went missing. For a flat text edit, the formatted-text panel below the tree holds the same data with 2-space indentation. To diff two payloads side by side, open the JSON Compare tool next.

Honest limitations

The viewer accepts strict JSON only: single quotes, trailing commas, comments, and undefined values are rejected with an error. Extremely large files (tens of megabytes) may scroll slowly on low-memory phones — paste a smaller slice first. Duplicate keys keep the last value, per the JSON standard.

Privacy and Client-Side Security

Privacy Guarantee: All parsing and rendering occur locally inside your browser. Your JSON text is never transmitted, stored, or recorded on remote servers.

Many online viewers send your payload to a server for formatting. TinyToolzz keeps everything in-page with plain JavaScript and the browser JSON parser.

Because nothing is uploaded, there is no waiting queue, no account, and no copy retained anywhere. Your data exists only in the tab memory and is discarded when you close the page or click Clear.

Frequently Asked Questions

What does the JSON Viewer do?
Paste raw JSON and the viewer parses it into an expandable tree. Each object and array becomes a collapsible node so you can open only the branches you need instead of reading one long line of text.
How do I find a key inside a large JSON file?
Type the key name in the search box. Matching keys are highlighted, non-matching branches dim, and a counter shows how many matches were found. Clear the box to restore the full tree.
How do I copy the path of a nested value?
Click any key or value in the tree. The path bar above the tree shows its exact location in dollar-bracket notation, for example $.store.book[0].title, with a button to copy it.
What happens when my JSON has a syntax error?
The tree clears and a red message names the exact line and column where parsing failed, for example a missing quote or a trailing comma, so you can fix that spot and visualize again.
Is my JSON data sent to a server?
No. All parsing and rendering runs locally in your browser with JavaScript. Your text is never transmitted, stored, or logged anywhere. Closing the tab or clicking Clear removes it from memory.
Can I copy or download the formatted result?
Yes. Use Copy Tree Text to copy the 2-space formatted JSON, or Download JSON to save it as a .json file. Both use the validated parse so the output is always correct.
