Frequently asked questions
Will recipients still be able to see the filename and creation date?+
Filename is set by the file system, not properties. Creation date is in core.xml — use the Core Metadata Wiper to clear it too.
Do I need to run both Core and App Wipers?+
For complete metadata removal, yes. Core Wiper handles author/date fields; App Wiper handles company/version fields.
Will this affect shared OneDrive or SharePoint files?+
The wiper operates on the local .xlsx file. Download from OneDrive/SharePoint, wipe, and re-upload the clean version.
