Data Anonymizer
Deterministic masking rules with counts. Preview before exporting.
What it does
Deterministic masking rules with counts. Preview before exporting. Part of Data & Business — CSV/JSON cleanup, conversion, and validation.
Also found under: mask, pii, anonymize, privacy.
When to use it
Mask emails and phone numbers in a support export before sharing it with a vendor.
Privacy & safety
Rule-based masking with per-rule counts. Always review the preview — masking is deterministic, not intelligent.
This tool works on text you paste — nothing leaves the page until you copy or save it yourself.
