Remove Excel Metadata Online – Privacy Cleaner

What Is Excel Metadata?

Excel metadata is hidden information automatically stored inside spreadsheet files. It may include author name, company name, computer username, creation date, modification history and comments. This data is invisible during normal viewing but can be accessed using software tools.

Why Removing Metadata Is Important

When Excel files are shared externally, metadata can unintentionally expose personal identity, internal project names or confidential information. Businesses often remove metadata before sending files to clients, government departments or publishing documents online.

Common Metadata Found in Excel Files

• Author and Last Modified By
• Company and Manager name
• Document title and subject
• Keywords and comments
• Creation and modification timestamps

How Excel Metadata Is Stored

Excel XLSX files are ZIP containers containing multiple XML documents. Metadata is stored inside core.xml and app.xml files, which preserve author and system information even after visible content is edited.

Manual Removal Is Not Reliable

Using Excel’s “Inspect Document” feature often fails to remove all metadata. Custom XML, hidden properties and system identifiers may still remain.

The Excel Metadata Cleaner rebuilds the workbook structure and resets all core properties, removing traces of previous authorship and restoring neutral file identity.
