JS Object Viewer
Paste a JavaScript object literal or JSON and view it as an interactive, collapsible tree - without executing any code.
Paste a JavaScript object literal or JSON below - this tool parses it safely (never executes it) and displays it as a collapsible tree.
This accepts both strict JSON and common JS object literal syntax (unquoted keys, single quotes) - your input is only ever parsed as data, never executed.
What Does This Tool Do?
It parses an object literal or JSON string and renders it as a navigable, collapsible tree - making it easier to explore deeply nested structures than scanning raw, unformatted text.
Why Use This Tool?
A deeply nested API response or configuration object is hard to read as flat text - a collapsible tree view lets you expand only the parts you care about.
How to Use It
- Paste a JavaScript object literal or JSON.
- Click View.
- Click any object/array node to expand or collapse it.
Important Notes
This tool parses your input as data only - it never uses eval() or executes any part of your input as executable code, so it's safe even for object literals containing what looks like function-like syntax (which is simply rejected as invalid data).
