FAQ

What is a JSON tree viewer?

A JSON tree viewer turns nested JSON into expandable objects and arrays so large payloads are easier to inspect.

Can I search inside JSON?

Yes. Use the search field to find matching keys or values in the parsed JSON tree.

Is uploaded JSON private?

Yes. JSON files are read and parsed in your browser without being uploaded.

When should I use JSON Viewer instead of JSON Formatter?

Use JSON Viewer for inspection and navigation. Use JSON Formatter when your main goal is formatting, minifying or validating raw JSON.
