This task is the removal of identifiers from a people-data extract of appraisal metrics, so no one is named. UK GDPR Recital 26 places anonymous data outside the rules. anonym.plus marks each name on your device, so the numbers stay rich while the staff stay private.
When this applies
An analyst loads an HR extract into a BI dashboard. You strip the identifiers first, so the feed clears Recital 26 before it leaves the HR system.
How anonym.plus handles it
- Open the data extract in anonym.plus on your device.
- Built-in OCR reads a scanned report page.
- The app marks names, emails, and IDs.
- Confirm the markings and keep the metric columns.
- Swap each identifier for a code.
- Save the cleaned feed locally.
What you need to provide
- The data extract (CSV-as-TXT, XLSX-as-TXT, PDF).
- An operator (Replace keeps metrics readable).
- Optional alias map, OFF for true anonymity.

Limitations & cautions
Quasi-identifiers can re-link a row. A rare mix of tenure, site, and role may match one person even with no name. Bucket such fields before you publish the dashboard.
Frequently asked questions
What is a quasi-identifier risk here?
A combination like tenure plus site plus role can match one person. Recital 26 and the motivated-intruder test treat that as non-anonymous, so bucket or coarsen those fields.
Does it keep the metric values?
Yes. Only names and contacts are coded, so the metrics stay rich for analysis.
Is the extract uploaded?
No. The tool works offline, so it stays on your device.
