Audit workpaper redaction is the removal of personal data from supporting audit evidence. Once a file is anonymous under GDPR Recital 26, it leaves that scope. anonym.plus runs locally and keeps the tests, samples, and conclusions whole.
When this applies
Workpapers hold sampled records that name customers and staff. To share them with a peer reviewer or archive them, you clear those names.
How anonym.plus handles it
- Load the workpapers into anonym.plus on your device.
- The tool flags customer, staff, and preparer names.
- Account and reference IDs get flagged too.
- Swap each confirmed item for a steady label.
- Save the clean workpapers on your device.
What you need to provide
- The workpapers (PDF, DOCX, XLSX, or export).
- An operator (Replace keeps the evidence readable).
- Optional allow-list for reference codes.

Limitations & cautions
Spreadsheets mix tidy columns with free-text notes. Column rules handle the first well. Note fields need the same review as any text, so test a sample before a full run.
Frequently asked questions
Can sampled records stay linkable?
Yes. A steady label map swaps each ID the same way, so rows for one customer still join while no real identity is left.
Will the test conclusions survive?
Yes. The tests, samples, and conclusions stay. Only personal data such as names and accounts changes.
Does it handle spreadsheets?
Yes. XLSX columns and free-text note fields are both supported, with a review pass on the notes.
