Frequently asked questions
Is JSON Formatter free?
Yes. ToolNest provides JSON Formatter as a free browser-based utility.
Does JSON Formatter require an account?
No account is required. Open the tool and use it directly in your browser.
What can JSON Formatter do besides pretty print JSON?
It can format JSON, compact JSON, validate syntax, repair common JavaScript-style JSON issues, sort object keys, filter by key or value, inspect a tree view, copy JSON paths, and export a small report.
Does JSON Formatter replace the input JSON or use a separate output box?
