Microsoft Excel is becoming the go-to productivity tool for an increasing number of reasons. Although we usually associate it with a data collection and transformation tool, it also offers features that help secure it or add another level of professionalism to your dataset.
One way to secure the contents in an Excel document is to add an electronic signature; it is an excellent way to establish data ownership and confidentiality by guaranteeing that a third party has not been involved in altering it.
In this article, we will describe different tools that allow you to sign your Excel document electronically. We will then focus on the “Signature Line” built-in feature and illustrate how to insert and remove the digital signature in Excel.
How to insert a signature in Excel?
In case you are working on an Excel version other than 2019 or 365, below we list two certificate authorities recommended by Microsoft and two signature platforms that are less official but more user-friendly.
Official certificate authorities
- GlobalSign is a Microsoft-recommended company that provides identity services, among others.
- IdenTrust is also a certificate authority recommended by Microsoft, which provides downloadable root certificates.
Electronic signing platforms
- AdobeSign integrates with most business apps, including Microsoft Excel. It allows you to insert a signature line as well as collect digital signatures in multiple documents.
- HelloSign can also be used for legally binding electronic signatures but is more intuitive for most users than the previous two options.
In all cases, you will need to pay an amount to be able to use the electronic signature in your Excel document. Luckily, Excel 2019 and 365 versions offer a native feature, “Signature Line”, whereby you can quickly and easily sign your document. If you work on a Mac, you cannot access this feature, so it’s recommended that you use one of the tools above to insert signatures into your Excel.
We will first explain how to insert the signature box using the Subject Line feature in Excel and then how to digitally sign with a visible or non-visible signature.

How to insert a signature in Excel using the Subject Line feature?

How to sign an Excel document using the Subject Line feature?

Note: In case you are using a tablet or tactile device, you can add a handwritten signature. You can sign your name directly in the box next to the X using an inking feature.
- 4. Once you insert your handwritten signature successfully, click “Sign”.
Excel will automatically inform you about the current status of your Excel document. “MARKED AS FINAL” means that this file should no longer be editable by anyone else other than the signer.
Now that you know how to successfully insert a signature line in Excel, let’s explore how to digitally sign an Excel document to choose between a visible or non-visible signature.
How to digitally sign an Excel document?

- 1. Go to File > Info > Protect Workbook > Add a Digital Signature.
- 2. In “Purpose for signing this document”, include the reason this document needs digital signing. Here, I will simply include “Invigilation”. Then, click “Sign”.
The “Signatures” button should now appear as well as the “Read-only” status.
