Signing a Workbook
Excel 2007 supports two types of digital signatures: a visible signature and an invisible signature.
To add a visible digital signature, choose Insert> Text> Signature Line> Microsoft Office Signature Line. Excel displays its Signature Setup dialog box, and you are prompted for the information for the signature.
After you add the signature box, double-click it to display the Sign dialog box, where you actually sign the document either by typing your name or uploading a scanned image of your signature.
