Questions and answers
Does the data go to a server?
No. Parsing and redaction run locally in your browser. The page does not upload the JSON.
What does redact mean?
Redact replaces values under sensitive keys such as token, password, api_key, and authorization with a visible placeholder.
Can I validate JSON here?
Yes. Submit valid JSON to format it; invalid syntax returns an error without sending the input anywhere.
Can I use this for production secrets?
Use it for inspection, but avoid pasting live credentials into any website. Rotate a secret if it was exposed.
