Alternatively, you can select the “Alt Text” option in the “Accessibility” group on the “Image Format” tab.
Either option will bring up the “Alt Text” window to the right of the window. Unlike the Alt Text window in Word and PowerPoint, Excel lacks the “Generate a description for me” option.
Instead, you need to create the description yourself. The general rule for alt text is to keep it short and descriptive. You can also omit unnecessary descriptions such as “image of” or “photo of” when screen reader announces the object to you.
If the item is purely decorative, then select it by checking the box next to “Mark as decorative.” Once selected, the box where you normally enter the description is grayed out and you can no longer enter a description. The purpose is to let the screen reader know that it can safely skip that object.
