Like the other Microsoft Office applications, you can use a spell check in Excel, too. This is handy for finding common typos or spelling errors.
Go to the “Review” tab and select “Spelling” in the Proofing section of the ribbon. When the spellcheck box appears, you’ll see the words in your spreadsheet that are not in the dictionary. You can ignore the spelling, add the word to the dictionary, change it manually, or use one of the suggestions.
