Frequently Asked Questions

Is my JSON data uploaded to your servers?
No. All JSON formatting and validation happens entirely client-side in your browser. Your data never leaves your device, ensuring complete privacy.
How does the JSON validation work?
We use native browser JSON parsing. If your JSON contains trailing commas, missing quotes, or syntax errors, the tool will instantly catch the error and prevent formatting until it is fixed.
