How to remove software version and company name from excel app properties
- Step 1Save the completed workbook — Finalise your .xlsx and save it before uploading.
- Step 2Upload and wipe app metadata — ExcelJS loads the workbook and sets all application property fields to empty strings.
- Step 3Download the clean file — Recipients cannot determine which software version or organisation produced the file.
Frequently asked questions
Why does it matter what Excel version is embedded?+
Exact version strings help attackers craft targeted exploits and give recipients IT-environment intelligence. For regulatory submissions, software version information may also be irrelevant or unwanted.
Does running both Core and App Metadata Wipers achieve a complete strip?+
Yes. Core Wiper removes author and edit history (core.xml); App Wiper removes software and organisation fields (app.xml). Run both for a complete property clean.
Can this be automated for batch processing?+
The browser UI processes one file at a time. Batch API automation is on the Developer tier roadmap.
