The proofing options in Office programs, such as Word or PowerPoint, include settings that you can apply to instruct the spelling checker to ignore certain types of words, including words written in capital letters, words that contain numbers, and words that are part of a URL (any web or file address). You can also specify whether the spelling checker flags repeated words.

You can find these settings in the Proofing dialog box of most Office programs. See Open the proofing options in your Office program below to learn how to access the proofing options in each Office program.
