Methods to Add a Signature in Excel

Here are two simple methods to add a signature to your Excel sheet:

A signature line allows you to add a designated space for a visible signature in your Excel file, often used for formal or professional documents. Here's how you can create and use a signature line:

Step 1: Open the Excel Document

• Open the Excel Document
• Select the Cell, where you want to insert the Signature

Step 2: Insert a Signature Line

• Go to the Insert tab on the Ribbon.
• Click on Text > Signature Line > Microsoft Office Signature Line.
• Fill in the required details in the pop-up dialog box, such as the signer’s name, title, and any instructions.
• Click OK to insert the signature line into your worksheet.

Step 3: Sign the Signature Line

• Right-click on the signature line and select Sign.
• Type your name or upload a digital signature image.
• You can also sign using a touchscreen or stylus if your device supports it.

If you don’t have a digital certificate, a pop-up will appear asking if you want to get a Digital ID. Simply select Yes and follow the on-screen instructions to set it up. Click here to know more.

Step 4: Remove the Background (Optional)

Click on the image, go to the Picture Format tab, and select Remove Background for a cleaner look.
