In Microsoft Excel, you can add a watermark, sort of, to an Excel sheet. How to do this is not intuitive. In Microsoft Word you have templates to chose from such as “Confidential” or “Do Not Copy” for a watermark.
I am going to discuss one method; adding an image background as a watermark. We are going to insert an image which could be a photo or a company logo. Let’s see how to implement this watermark.
This is for Excel for Office 365 Windows and Mac versions. Other versions of Excel will be similar.
Your Excel Sheet
- Create an Excel spreadsheet or use an existing one. Refer to my newly created sheet (Sheet1) below:

- Click Insert>Text>Header & Footer

- Select Picture
Select Your Watermark
Select your option for inserting a picture. Refer to following screenshot

- Select your image
- Click Insert
- You will see &[Picture] in the Header.

View Your Watermark
- Tap anywhere outside the Header to see your watermark. Refer to following screenshot for my selection of a logo:

Formatting Your Watermark
To format the image:
- Tap anywhere outside the Header
- Click Insert>Text>Header & Footer
- Select Format Picture. You will see the following screen:

From here you can resize the image
- Click the Picture tab
- Select the Color box and change it to the Washout option
- Click OK. This allows the background image to be less intrusive.

Refer below to my final capture of the watermark screen:

- Save your spreadsheet and close or exit Excel
For a Microsoft Word look-a-like watermark, use the WordArt feature in Excel.
