Frequently asked questions
Does the formatter send my JSON to a server?
No. The formatter runs in the browser, so your payload stays on the page while you work with it.
What happens if the JSON is invalid?
The tool shows an error state instead of formatting broken JSON, so you can fix the payload first.
Can I minify JSON too?
Yes. The same tool can produce compact one-line JSON for quick copying or testing.
