उपयोग कैसे करें
How to use
- Paste a JSON object or array into the editor.
- Select View JSON tree to parse the value locally.
- Expand or collapse branches and copy a path when you need to reference a value.
Readable nested data
Objects and arrays are rendered as expandable branches with property names, array indexes, primitive types, and compact values. Long strings are trimmed in the tree while the full value remains available in its path.
Private browser processing
The viewer uses JSON.parse in your browser and never sends pasted content to a server. Input is limited to 2 MB so large documents remain responsive.
Frequently asked questions
You may also want to know
Can I view arrays as well as objects?
Yes. Array items appear with numeric indexes and can contain their own nested objects or arrays.
Can I copy a value path?
Yes. Select Copy path on any tree row to copy a JSONPath-like reference such as $.users[0].name.
Is my JSON uploaded?
No. Parsing and rendering happen locally in your browser.
