Batch hides sensitive data or text from a Word document

Author Sun Last modified

When using Word to draft documents such as financial reports, legal briefs, or collaboration agreements, you may want to redact sensitive data like company names or figures before sharing or publishing them online, to prevent data leakage. Manually identifying and hiding this information can be time-consuming and prone to errors. To solve this, Kutools for Word developed the AI Data Redaction feature, which leverages AI to automatically redact or replace sensitive data in bulk, helping you protect privacy more efficiently.

What AI Redaction Does:

  • ✅ One-click automatically identifies and lists types of sensitive data like amounts, IDs, names, and addresses.
  • ✅ Allows manual addition of custom sensitive data categories and lists words based on those categories.
  • ✅ Highlights selected sensitive words, with real-time updates to the document when words are deselected for easier review.
  • ✅ Offers one-click redaction of all selected words, creating a new document with redactions while preserving the original.
  • ✅ Provides multiple color options for redaction.
