Word and PowerPoint anonymization

Anonymize Word and PowerPoint files, layout intact

NymData detects and anonymizes PII in body text, tables, headers, footers and speaker notes.

It is replaced directly in the file: styles, images and layout stay the same.

Processing stays on your servers.

How do you anonymize a Word document?

You need to process the whole document, not just the text you see on screen.

Tables, headers, footers and file properties often contain names.

With NymData, you select a document or a folder.

PII is anonymized directly in the file, with formatting preserved.

An audit report documents the run.

The trap

What "Find and Replace" misses

Replacing names by hand in Word or PowerPoint almost always leaves traces: spelling variants, forgotten phone numbers.

Above all, it misses areas nobody ever looks at:

  • Headers and footers: the employee's or customer's name, repeated on every page.
  • Speaker notes: invisible during the slideshow, but sent along with the file.
  • File properties: the document author stays recorded.

Speaker notes

The slide looks harmless. The notes, however, travel with the file: NymData analyzes them too.
What NymData does

An anonymized document that keeps its look

The whole Word document

Paragraphs, tables, and the headers and footers of every section go through the detection engine.

The whole presentation

Text boxes, tables and speaker notes on every slide are analyzed.

Formatting preserved

Only the sensitive text changes.

Styles, fonts, images and tables stay in place, even when a piece of data is split by a style change.

Your choice of method

A label ([PERSON]), a realistic fake name to keep the text natural, or a constant identifier. Compare the methods

Author erased

The author saved in the file properties is erased from the anonymized document.

Source file never modified

NymData creates an anonymized copy in a separate folder, on your servers.

An audit report documents the run.

Use cases

When should you anonymize your documents?

  • Human resources: reviews, employee files and letters sent to an outside firm, an attorney or an auditor.
  • Legal: contracts, briefs and exhibits shared with a third party.
  • Presentations: customer decks reused for training, demos or responding to an RFP.
  • Archives: documents past their retention period, anonymized instead of deleted, thanks to scheduled processing.
