BYTETOOLS

JSON Viewer

View JSON as a collapsible interactive tree online. Expand and collapse nodes, search keys and values, and copy the JSONPath of any node privately.

What is the JSON Viewer?

The ByteTools JSON Viewer renders any JSON document as an interactive, collapsible tree. Every node shows a type badge and array length, branches expand and collapse with a click (or all at once), and a search box highlights matching keys and values while automatically opening the branches that contain them.

  • Collapsible tree with expand/collapse-all controls
  • Type badges and array/object length counts on every node
  • Live search across keys and values with auto-expanded matches
  • Copy the JSONPath of any node with one click
  • Node and size statistics for the whole document
  • 100% private — JSON never leaves your browser

How to use the JSON Viewer

  4. 4

About the JSON Viewer

The ByteTools JSON Viewer renders any JSON document as an interactive, collapsible tree. Every node shows a type badge and array length, branches expand and collapse with a click (or all at once), and a search box highlights matching keys and values while automatically opening the branches that contain them.

Unlike our JSON Formatter, which re-indents JSON as text, this viewer is for exploring structure: drill into deeply nested API responses, count items at a glance, and click the copy icon beside any node to grab its JSONPath — like $.store.books[0].title — for use in code, jq-style queries or test assertions.

The viewer runs 100% locally in your browser. Documents are parsed with JavaScript on your machine and never uploaded or stored, so it is safe for production API responses and private exports.

Frequently asked questions

What is the difference between a JSON viewer and a JSON formatter?

A formatter re-indents the raw text; a viewer parses the document and shows it as an interactive tree you can fold, search and navigate. Use the viewer to understand structure and find values, and the formatter when you need clean text output.

How do I find a key inside a large JSON file?

Type part of the key or value into the search box. Matching nodes are highlighted and every branch on the path to a match is expanded automatically, so you can see exactly where each hit lives in the structure.

How do I copy the path to a JSON value?

Hover over any node and click the small copy icon. The tool copies a JSONPath expression such as $.data.items[2].id, which you can use in code, tests or query tools.

Is there a size limit?

The tree view is capped at about 20,000 nodes to keep the page responsive. For bigger documents the tool tells you instead of freezing — use the JSON Formatter for plain re-indenting of very large files.

Is my JSON uploaded to a server?

No. Parsing and rendering happen entirely in your browser tab. Nothing is transmitted, logged or stored, so confidential API responses stay private.
