Remove the author from an Excel file
Every .xlsx carries a creator name, a last-modified-by name, often a company field, and timestamps for the whole editing history. Forward a spreadsheet two departments over and its properties still say exactly who built it and when.
This page opens the metadata tool on your workbook, shows what it's carrying grouped by risk, and exports a copy with the identity fields removed. The output package is reparsed to verify the fields are actually absent.

This is Excel Metadata Remover preconfigured for this task — open the full tool for every option.
How it works
Select an .xlsx file. Document properties are parsed locally.
Review creator, last-modified-by, company, title, timestamps, and custom properties.
Export a cleaned copy with identity fields removed.
The output is reparsed to confirm the fields are gone.
What the tool does
- Reads core properties (creator, lastModifiedBy, dates) and extended properties (company, application)
- Reads custom document properties
- Strips identity and history fields in a rewritten package
- Post-export verification with before/after field counts
How the result is verified
The cleaned file is reparsed and all targeted property fields are read back; verification passes only when they are absent or empty.
Frequently asked questions
What identifies me in a spreadsheet's properties?
Typically your name twice (creator and last modified by), your organization's name, the exact Office version, creation and modification timestamps, and total editing time. Enough to unmask an anonymous file completely.
Does this change my data?
No, cells are untouched. Only the document property parts of the package are rewritten, and the verification compares the data before offering the download.
