Native-file redaction is the removal of personal data from documents in their original format, which you may produce under FRCP 34. anonym.plus runs locally on Word, Excel, and PDF files, so the content stays usable.
When this applies
Some productions call for the original format to keep formulas or comments alive. Those same files hide names in cells, comments, and tracked changes.
How anonym.plus handles it
- Open the file in anonym.plus on your device.
- It scans cells, comments, notes, and tracked changes.
- The tool flags names, contacts, and IDs in each area.
- Confirm the flags, including hidden comment text.
- Replace or mask each confirmed value.
- Save the clean document on your device.
What you need to provide
- The file (DOCX, XLSX, PPTX, or PDF).
- An operator; Replace keeps the document usable.
- Optional rules to keep non-PII codes and formulas.

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
Why produce native files at all?
The original format keeps formulas, comments, and structure that an image loses. FRCP 34 lets parties specify the form, and it is sometimes required.
Does it catch hidden cells and comments?
Yes. The tool scans comments, notes, hidden rows, and tracked changes, where names often hide.
Can I keep formulas while clearing names?
Yes. An allow-list keeps non-PII codes and formulas while personal data is swapped out.
