How to use PII Detector & Redactor
Paste any text, JSON, or CSV and find personally identifiable information you may need to remove before sharing or logging. Useful for GDPR/CCPA data subject requests, HIPAA review, PCI-DSS scrubbing, and bug-report sanitization.
What it detects
- Email addresses, phone numbers (international and US formats).
- US Social Security Numbers (SSN) and basic government identifier patterns.
- Credit card numbers — optionally Luhn-validated to reduce false positives.
- IPv4 / IPv6 addresses and MAC addresses.
- IBAN bank account numbers.
- Date of birth-like patterns and US ZIP codes.
Tips & pitfalls
- Regex-based detection is best-effort: validate before sharing the redacted output externally.
- Names and addresses are NOT detected here — pattern matching is unreliable for free-form names.
- Toggle Luhn validation off if you need to flag possible card-shaped numbers without arithmetic checks.
