Open the excel document you wish to inspect for hidden data or personal information.
From the Office Button menu, select Save As. To save a copy of your original document, enter a name in the "File name" field.
Note: It's a good idea to use the Document Inspector on a copy of your original document, because it's not always possible to restore the data that the Document Inspector removes. In the copy of your original document, from the Office Button menu, select Prepare, and then click Inspect Document.
In the Document Inspector dialog box, select the checkboxes to choose the types of hidden content that you want to inspect. For more information about the individual Inspectors, see Remove hidden data and personal information from Office documents at the Microsoft Office Online web site.
Click Inspect. Review the results of the inspection in the Document Inspector dialog box. Click Remove All next to the inspection results for the types of hidden content that you want to remove from your document.
