Removing Personal Information
As you create a workbook in Excel, there is a lot of information that is stored with the workbook that can identify you as the author. Most of this information is stored in the workbook's file properties. Excel provides a handy tool that allows you to remove the personal information you don't want others to see. This tool is called the Document Inspector.
To use the Document Inspector, open the workbook you want to evaluate and then use one of the following, depending on the version of Excel you are using:
In Excel 2010, 2013, and 2016, display the File tab of the ribbon, click Info | Check for Issues | Inspect Document.
Or, if you're using Excel 2016, you can use the Tell Me box. Click into the box and begin typing "Prepare for Distribution." From the fly-out, choose Inspect Document (or other selection as necessary).
Excel displays the Document Inspector dialog box, which is just a series of check boxes. You use these check boxes to indicate the items you want the inspector to look for. When you click Inspect, Excel tries to find them and then displays a dialog box showing the findings.
When presented with the Document Inspector's findings, you can choose which items you want removed from the workbook.
