What Is the JSON Viewer?
The JSON Viewer is a free, professional tool for parsing, exploring, and formatting JSON data. Paste any JSON string or upload a file to see it rendered as an interactive tree with expandable/collapsible nodes, syntax highlighting, and search functionality — all running entirely in your browser.
Unlike online JSON viewers that upload your data to servers, this tool processes everything locally. Your data never leaves your device.
Key Features
- Interactive Tree View — Explore JSON as a collapsible tree. Objects and arrays are rendered as expandable nodes with item counts.
- Syntax Highlighting — Strings (red), numbers (green), booleans (teal), null (purple), and keys (blue) are color-coded.
- Click to Copy Path — Click any key in the tree to copy its full JSON path ($.parent.child[0].key) to clipboard.
- Search with Highlighting — Search for keys or values with real-time yellow highlighting. Parent nodes expand automatically.
- Format & Minify — Pretty-print JSON with 2-space indentation or compress to a single line with one click.
- File Upload — Load .json files directly from your filesystem.
- Statistics — Shows total items, character count, and nesting depth.
- Expand/Collapse All — Toggle all tree nodes open or closed.
- Settings Memory — Your input is saved in localStorage between sessions.
- 5-Language Support — English, Arabic, Spanish, Portuguese, Chinese.
Use Cases
- API Debugging — Paste API responses to visualize and explore nested JSON structures.
- Configuration Review — Load config files and navigate complex settings hierarchies.
- Data Analysis — Explore JSON datasets, search for specific fields, copy paths for code.
- Learning — Students can visualize JSON structure to understand nested data.
Privacy & Security
This tool runs 100% in your browser. No JSON data is ever sent to a server.
