Six ways to look at the same JSON
Pretty
A collapsible, syntax-highlighted tree.
Table
Arrays of objects normalized into a spreadsheet-style table — export to CSV or Excel.
Relationship
See how nested arrays link together as separate tables.
Structure
Infer TypeScript, Go, Python, PHP, Java, Kotlin, Rust, or C# types from the JSON's shape.
XML
The same data as XML, instantly.
YAML
The same data as YAML, instantly.
How it works
Navigate to a JSON URL
Open any URL that returns raw JSON and the page is automatically replaced with the viewer — no clicking required.
Or paste it manually
Click the toolbar icon to paste JSON from anywhere — handy for responses copied out of DevTools' Network tab.
Your data stays yours
Everything runs locally in your browser. Nothing you view is collected, logged, or sent anywhere.
