Office anonymization
Anonymize Excel
Detect and redact personal data in Excel and ODS sheets without losing tabular structure for internal analysis.
Spreadsheets pack identifiers, amounts and addresses into dense columns. Excel anonymization runs detection while respecting cells and sheets so teams can keep filtering without exposing PII to third parties.
Combine patterns, word sets, whitelist/reverse and local European AI. Amount and address detectors are especially useful in finance and logistics; dates help on customer histories.
If the table lives in a PDF, convert with PDF to Excel then anonymize. For decks or prose, use the PowerPoint and Word landings.
