Json Viewer
View and explore JSON data in an interactive tree format. Expand, collapse, and search through complex structures. Fast, private, works in your browser.
Interactive JSON Exploration
JSON data can be deeply nested and difficult to read in plain text. Our interactive viewers present JSON as navigable trees, making it easy to explore complex structures, find specific values, and understand data relationships.
Tree View Navigation
Collapse and expand objects and arrays to focus on relevant sections. Large responses from APIs or database exports become manageable when you can hide irrelevant branches and drill into specific paths.
Search and Filter
Find specific keys or values across large JSON documents. Search highlights matches and can filter to show only matching branches. This is invaluable when debugging API responses or searching configuration files.
Path Copying
Click any value to copy its full path (e.g., data.users[0].email). This helps when writing code to access specific values or when communicating about data structure with team members.
Use Cases
- API debugging: Inspect responses, find error messages, understand structure
- Configuration review: Navigate complex config files, verify settings
- Data analysis: Explore exports, understand schema, find anomalies
