No. The JSON Viewer runs entirely in your browser; your data is never sent to a server.

Can I query JSON with JSONPath?

Yes. Switch to the JSONPath tab and use expressions like $.users[0].name, $.items[*].id, or $..email (recursive descent) to extract matching values, with a live result count.

Can it generate a JSON Schema?

Yes. The Schema tab generates a draft-07 JSON Schema from your sample data, inferring types, properties, and required fields, which you can copy or download.

Can I compare two JSON documents?

Yes. The Compare tab shows a structural diff listing every added, removed, and changed path between the two documents.

What's the difference from the JSON Formatter?

The Viewer shows an interactive tree plus JSONPath, schema, and compare tools, while the Formatter focuses on pretty-printing, minifying, and converting JSON text. Both validate your JSON.

Yes — free, no signup, and no limits.

What is Json Viewer?

JSON Viewer validates JSON and displays it as a collapsible, color-coded tree in your browser. Paste any JSON to instantly see whether it's valid, then expand and collapse nodes to explore deeply nested data. It runs entirely client-side, so your JSON is never uploaded and stays private on your device.

How to Use

1
Paste your JSON
Paste raw or minified JSON into the input area.
2
Check validity
See an instant valid/invalid status with the exact parse error if any.
3
Explore the tree
Click nodes to collapse or expand, and copy the formatted output if needed.
