Surprisingly, Excel doesn’t have a built-in watermark function. A lot of people just give up when they don’t see specific built-in features. However, most programs have workarounds that allow users to do more than the basics that their editing tools allow.
Because of this, and because of the way Excel is built, this means that you can use your own images, logos, or even text to create a watermark and add it to your project. The process is quite simple. Here’s the step-by-step guide.
1. Creating the Watermark
First you have to click on the Insert button on the top toolbar. After that, you have to select the Header & Footer menu.
The header should appear above the top row of your worksheet.
