Anonymized Output

Ready to redact

Your data stays in the browser. Paste JSON left to automatically hash and obscure PII.

Secure Client-Side Redaction

Sharing JSON payloads from production databases with vendors, support teams, or third-party developers carries a significant security risk. This tool recursively scans your JSON hierarchy and applies Regex patterns to detect Personally Identifiable Information (PII).

Everything happens entirely in your local browser memory. No data is sent to our servers, ensuring complete compliance with GDPR and HIPAA when cleaning diagnostic data.

What Gets Redacted?

Emails

Standard email addresses matching the user@domain.com format are obscured.

Phone Numbers

US and international phone formats (e.g., +1-555-0123).

Credit Cards & SSN

16-digit PANs and standard Social Security Number formats.

Sensitive Keys

Any JSON key containing words like password, token, or secret is completely blanked out.

After anonymizing, compare the original and redacted versions to verify nothing was missed. Use the JSON Viewer to inspect every nested field.

The default regex patterns cover the most common PII types. For custom patterns, you can modify the output after initial anonymization.
Yes. The JSON redaction and Regex-based PII detection run entirely in your local browser sandbox. We never see your original JSON, your resulting cleaned data, or your private API keys.
