Question 1

What personal information does the PII Masker detect?

Accepted Answer

It detects and masks email addresses, phone numbers, Social Security numbers (SSN), credit card numbers, IP addresses, and names. Detection uses pattern matching to find PII across all columns in your file.

Question 2

How does PII masking work?

Accepted Answer

Detected PII values are replaced with masked versions that preserve the format but hide the data. For example, 'john@example.com' becomes '****@****.com' and '555-123-4567' becomes '***-***-4567'. This maintains data structure while protecting privacy.

Question 3

Is my data safe during PII masking?

Accepted Answer

Absolutely. All processing happens locally in your browser. Your file is never uploaded to any server. This is critical for handling sensitive data — the PII never leaves your device.

Question 4

Can I use the masked data for testing or development?

Accepted Answer

Yes. That's a primary use case. Masked data retains the structure and format of the original, making it suitable for development, testing, demos, and sharing without exposing real personal information.

Question 5

Does it comply with GDPR or HIPAA requirements?

Accepted Answer

The tool helps with data minimization by removing identifiable information from datasets. However, compliance depends on your overall data handling process. Since no data leaves your browser, there is no third-party data processing involved.
