JSON Viewer – Inspect JSON Structure Online | MZ Smart Tools House

Open valid JSON in a readable expandable tree without sending the data to a server.

Inspect objects, arrays, strings, numbers, booleans and null values from real JSON input.

How it works

The viewer parses input with JSON.parse and renders the resulting structure without evaluating code.

{"user":{"name":"Mujtaba"},"active":true}

No. JSON requires JSON syntax such as double-quoted property names.

No. The tool parses data; it does not execute it.
