How to Underline or Highlight Spelling Errors in Excel

[Do the math]

How can I underline or highlight spelling errors as I am entering text data ? Can I do this without a script? If so please tell me how. If I need a script THANK YOU IN ADVANCE if you would kindly share it with me. Thanks

Excel doesn't work like Word. You can spell check, but it doesn't spell check on the fly nor highlight incorrect words.
