JSON Formatter FAQ
Is my data safe?▼
Yes. All processing happens locally in your browser. Your data is never sent to any server.
What happens if my JSON has syntax errors?▼
The tool highlights the exact error location and explains what's wrong, helping you fix it quickly.
Is there a size limit?▼
Since it runs in the browser, there's no strict limit. Very large files may cause the page to slow down.
