How It Works
Fast, secure, browser-native JSON processing in 3 simple steps
Paste JSON Text
Paste raw JSON into the viewer or load an existing .json file.
Expand & Search Nodes
Navigate branches with collapsible toggles and real-time key filters.
Copy Paths or Export
Copy JSONPath queries or download clean formatted files.
Visual Tree Navigation for Deeply Nested JSON Payloads
Tree View gives you full visual control over complex nested JSON structures. Expand only the branches you need, filter by key or value, inspect data types at a glance, and extract JSONPaths for API testing, unit tests, and query construction.
By transforming raw text into an interactive, visual hierarchy, JSONForge makes it easy to understand the architecture of any data payload. Whether reviewing complex Kubernetes pod definitions, nested GraphQL query responses, or multi-dimensional analytics dumps, our tree viewer eliminates guesswork and visual fatigue.
🌳 Interactive Nodes
Quickly fold and expand parent and child nodes with visual depth guides and item count badges.
🏷️ Color-Coded Types
Distinguish strings, numbers, booleans, arrays, objects, and null values with clear visual type indicators.
⚡ Fast Live Search
Find matching keys and values across thousands of nodes in milliseconds using real-time search filtering.
