Native File Redaction with anonym.plus

Clear PII from native Office files while their format stays usable.

In simple terms, PII redaction is the on-device process of finding and masking personally identifiable information in a document before it is shared.

Native-file redaction is the removal of personal data from a document in its original format. FRCP 34(b)(2)(E)(iii) says a party need not produce the same item in more than one form. anonym.plus reads the hidden layers a native carries, on your own device.

When this applies

A native keeps what an image drops: comments, tracked changes, hidden rows, speaker notes, and cached pivot sources. Rule 34(b)(1)(C) lets the requester ask for that form. Each of those layers can name someone the reader never sees.

How anonym.plus handles it

  1. Open the file in anonym.plus on your device.
  2. It scans cells, comments, notes, and tracked changes.
  3. The tool flags names, contacts, and IDs in each area.
  4. Confirm the flags, including hidden comment text.
  5. Replace or mask each confirmed value.
  6. Save the clean document on your device.

Limitations & cautions

Such files hide data in comments, hidden rows, and revision history. Confirm those layers are scanned. Producing original format can expose more metadata than an image, so weigh whether a static export fits the request better.

Frequently asked questions

Is a cut inside a native file safe?

Only if the value is removed rather than covered. A shape over a cell, a hidden column, or white text all leave the data in the file. Use Redact so the characters go, or hand over an imaged form for the items you had to mark.

Which hidden layers get scanned?

Comments, tracked changes and revision history, hidden rows and columns, speaker notes, and cached pivot sources. That is where names survive a visual check.

Can I keep formulas while clearing names?

Yes. An allow-list keeps non-PII codes and formulas while personal data is swapped out.
