What is JSON Viewer?
The JSON Viewer displays JSON data in an interactive, collapsible tree structure — letting you explore complex, deeply nested APIs and configurations by expanding only the branches you need, searching for specific keys or values across the entire dataset, and reading data types and object structures at a glance without parsing raw JSON text.
Complex API responses can return hundreds of nested properties across dozens of levels. Reading these as raw text — tracking bracket pairs, counting nesting depths, and finding specific fields — is slow and mentally taxing. The tree view maps the entire data hierarchy into an intuitive expandable interface, the same kind of structure used in browser DevTools. It dramatically reduces the time needed to understand unfamiliar API responses, debug data structures, or verify that JSON-LD schema markup is correctly formed before deployment.
Why Use JSON Viewer?
Raw JSON from production APIs, database exports, and JSON-LD schema blocks is dense and difficult to navigate without visual structure. The tree view maps the data hierarchy into an intuitive expandable interface — the same kind your browser DevTools uses. It dramatically reduces the time needed to understand unfamiliar API responses, debug data structures, or verify that schema markup properties are correctly nested before deploying to production.
Key Features of JSON Viewer
- ✓Interactive collapsible and expandable tree view for any depth of nested JSON
- ✓Full-text search across all keys and values, highlighting every matching node
- ✓Colour-coded data types: strings, numbers, booleans, null, arrays, objects
- ✓Shows array length and object key count at collapsed nodes for quick orientation
- ✓Copy any individual value or entire subtree to clipboard with one click
- ✓Optimised for large JSON files — heavy nodes collapse automatically on load
How to Use JSON Viewer
- 1
Paste your JSON data
Enter your JSON — API response, config file, or JSON-LD schema block — into the viewer input.
- 2
Explore the tree structure
Click the expand arrows to open nested objects and arrays. The root level is expanded by default.
- 3
Search for a key or value
Type in the search box to find any key name or value across the entire structure. Matching nodes highlight instantly.
- 4
Read data types and counts
Collapsed nodes show their type (Object, Array) and item count, helping you understand data shape before expanding.
- 5
Copy what you need
Click any value to copy it, or select a subtree to copy the entire nested object as a JSON string.
