Features

🪜

Guide-Line Diagram

Every branch draws classic tree connectors so parent-child links stay visible in deep payloads.

🎯

Drill-Down Focus

Re-root the diagram at any object or array and walk back up with one click per breadcrumb level.

🎚️

Depth Slider

Expand exactly 1 to 10 levels. Outer shape first, details on demand — ideal for huge configs.

🔒

Local Device Privacy

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

How to Use the JSON Tree Viewer

  1. Paste raw or minified JSON into the Input JSON box, or click Load Sample.
  2. Set Expand to depth (start at 3 for large files) and click Draw Tree.
  3. Click any row to collapse or reopen it. Click ⤢ on an object or array to drill into that branch.
  4. Use the breadcrumb above the diagram to jump back to any parent level or the root.
  5. Type in Search branches to highlight matches, then Copy View or Download JSON to export the focused branch.

Seeing Structure Instead of Text

Formatted JSON still forces you to count braces to know which level a key sits on. The diagram replaces indentation guessing with explicit connectors: each row shows its branch glyph, a collapse toggle, a type tag with child counts, and a drill-in button for containers.

When the diagram wins

Use it for payloads deeper than three levels, configs with repeated blocks (per-region settings, per-user permissions), and any file where you only care about one subtree. For flat key inspection with JSON paths, the JSON Viewer list is faster; for spotting edits between versions, use JSON Compare.

Honest limitations

Strict JSON only: single quotes, trailing commas, and comments are rejected with an error. Diagrams over roughly 5,000 rows are truncated to the first 5,000 to protect phone browsers — drill into a branch to see the rest. Depth beyond 10 renders collapsed by default.

Privacy and Client-Side Security

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

Many online diagram tools send your payload to a server for layout. 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 is the difference between JSON Viewer and JSON Tree Viewer?
JSON Viewer shows a collapsible nested list with search and JSON-path lookup. JSON Tree Viewer draws a diagram with guide lines, a depth slider, and drill-down focus so you can isolate one branch of a large payload at a time.
How does drill-down focus work?
Click the focus button on any object or array row to re-root the diagram at that branch. A breadcrumb above the diagram shows the full path back, and each segment jumps straight to that level.
What does the depth slider control?
It sets how many levels the diagram expands automatically, from 1 (top-level keys only) to 10 (fully expanded). Deeper branches collapse into summary rows you can still open individually.
How do I copy just one branch of the JSON?
Drill into the branch with its focus button or click its copy button to copy that subtree as formatted JSON. The main Copy button always copies the currently focused view.
What happens when my JSON has a syntax error?
The diagram clears and a red message names the exact line and column where parsing failed, so you can fix that spot and visualize again.
Is my JSON data sent to a server?
No. All parsing and diagram rendering runs locally in your browser with JavaScript. Nothing is transmitted, stored, or logged anywhere. Closing the tab or clicking Clear removes it from memory.
