How To Add Digital Signature To Excel In Excel

Adding a digital signature to an Excel document is an essential step for validating the integrity and origin of the spreadsheet. It's a security measure to ensure that the data is not tampered with and can be trusted by its recipients.

While Microsoft Excel provides a way to insert digital signatures, users often seek simpler and more intuitive solutions.

This guide will walk you through the process of adding a digital signature to an Excel file and explore why Sourcetable offers a more user-friendly approach than the native Excel functionality.

Adding Digital Signature to Excel

Understanding Digital Signatures in Excel

Digital signatures in Excel ensure the authenticity, integrity, and origin of a workbook. They confirm the identity of the signer and assure the workbook has not been altered. These signatures, available in Excel 2003 and later versions, apply to both Excel workbooks and templates. However, Excel versions prior to 2002 cannot recognize digital signatures.

Obtaining a Digital Certificate

To digitally sign an Excel workbook, a digital certificate is necessary. Commercial certification authorities, internal security administrators, or the SelfCert.exe tool from Microsoft Office can provide this. Remember that creating personal certificates with SelfCert.exe is for testing purposes only.

How to Add a Digital Signature

Digital signatures in Excel require specific steps based on the version you use. Adding a signature makes the document read-only, ensuring the signed version remains unchanged. If a workbook is modified post-signing, Excel removes the digital signature.

Excel's Signature Line Feature

The Signature Line command on Excel\'s Insert tab allows adding signature lines, customized via the Signature Setup dialog. Though Excel lacks built-in compliance checks, dedicated e-signature tools offer more comprehensive functionalities.

Signing Macro Projects

Excel allows digital signing of macro projects within the workbook. However, be aware that once signed, no changes can be made to the macro projects in a shared workbook setup.

Finalizing the Signature Process

After signing, Excel's Signatures Message Bar alerts if documents remain unsigned. Invisible digital signatures can be added for enhanced protection. Each digital signature added also includes a visible representation on the document, further certifying the signer's identity and content integrity.
