Format and validate JSON online

What does a JSON formatter do?

A JSON formatter adds consistent indentation and line breaks to compact JSON, making API responses, configuration files, and logs easier to read and debug.

Is my JSON uploaded?

No. Formatting, validation, and minification run locally with your browser's JavaScript engine, so pasted data is never sent to BeyUtils.

Formatter or minifier?

Use formatting while reviewing or editing data. Use minification when you need a smaller single-line JSON document for transport or storage.
