Frequently Asked Questions
What does the JSON Formatter do?
It formats (pretty-prints) raw or minified JSON into a human-readable indented format, and validates whether the JSON is valid.
Can it minify JSON too?
Yes. Use the Minify option to compress your JSON into a single line, ideal for reducing payload size in APIs.
Is there a size limit for JSON input?
No. You can paste JSON of any size. Processing happens entirely in your browser.
Is my JSON data sent to a server?
No. All formatting and validation happens locally in your browser. Your data never leaves your device.
