JSON Tools
Censor JSON
Censor JSON automatically identifies and masks sensitive fields in your JSON data. Detects common patterns like passwords, API keys, tokens, emails, SSNs, credit cards, and more. Supports multiple redaction styles (asterisks, [REDACTED], partial masking, hash) and custom patterns for application-specific fields.
JSON Censor
Redact Sensitive Data from JSON
Automatically detect and mask passwords, tokens, emails, and other sensitive fields before sharing.
Add custom key names to censor. Supports partial matches and regex patterns (wrap in /pattern/).
Tip: Use this tool to sanitize JSON before sharing logs, config files, or API responses. The default patterns detect common sensitive fields like passwords, tokens, emails, and credit card numbers. Add custom patterns to match your application-specific sensitive fields.
