Interactive PII Removal Explorer

See PII removal in action! Use the interactive explorer below to step through 6 stages of data transformation. Watch as credit cards, emails, IP addresses, and other PII are progressively removed or anonymized.

How to Use This Explorer​

  1. Navigate using arrow keys (← →) or click the numbered stage buttons
  2. Compare the Input (left) and Output (right) JSON at each stage
  3. Observe how fields are removed (red strikethrough) or transformed (green highlight)
  4. Inspect the YAML code showing exactly what processor was added
  5. Learn from the stage description explaining the technique and compliance benefit
