Metadata Removal

DOCX

DOCX files are essentially a ZIP archive containing XML files

1. Make a backup of your file first.

2. Rename the file extension from .docx to .zip

3. Unzip it.

Files containing metadata

• core.xml --> contains author, creation date, etc.

• app.xml --> contains application-specific metadata

• custom.xml --> may contain custom properties

1. Delete the sensitive content from these files.

• Re-zip the contents: zip -r ../clean_document.docx * from inside the folder.

• Rename back to .docx
