Highlights

• Per-column keep, replace, pattern-replace, shift, resample, generalise, sanitise, clear, and drop controls.
• Stable dummy mappings and pattern-aware replacements.
• Numeric distribution and representative-coverage handling for useful test data.
• Confirmed relationship controls and linked multi-table dataset generation.
• Quality reports with PASS, REVIEW, FAIL, and NOT EVALUATED outcomes.
• CSV/TSV export safeguards and a self-contained offline HTML build.

Privacy and limitations

Dummy Data Lab provides best-effort masking, sanitisation, and pseudonymisation. It is not certified anonymisation, differential privacy, or a statistical synthetic-data model. Free text, rare combinations, high-fidelity structure, and ambiguous dates can still require manual review. Use only data you are authorised to process and review generated output before sharing it.
