Frequently Asked Questions
What does a JSON formatter do?
It converts compact or minified JSON into readable, indented JSON so objects, arrays, and nested values are easier to inspect.
Can the formatter fix invalid JSON?
The formatter can show syntax problems and format valid JSON. For malformed input, fix the reported issue first or use a repair-focused workflow if available.
Is my JSON data sent anywhere?
No. Formatting runs locally in your browser, which is useful when inspecting private API responses, config files, or test data.
