Spell-checking Uppercase Words

by Allen Wyatt
(last updated March 7, 2015)


Excel includes a powerful spell-checker that, in reality, does a pretty good job. You can use this tool to locate potential spelling errors in your worksheets. If your worksheets contain lots of acronyms, you'll find that Excel flags most of them as misspelled words.

You can make sure that Excel ignores uppercase words in any spell-check by following these steps:

  1. Display the Excel Options dialog box. (In Excel 2007 click the Office button and then click Excel Options. In Excel 2010 and Excel 2013 display the File tab of the ribbon and then click Options.)
  2. At the left side of the dialog box click Proofing. (See Figure 1.)
  3. Figure 1. The Proofing options of the Excel Options dialog box.

  4. Make sure the Ignore Words in UPPERCASE check box is selected.
  5. Click on OK.

The only downside to this, of course, is if you use all uppercase for section titles or for other special words. In this case, Excel still ignores them, since they are uppercase. Make sure you change the setting of this check box based on the type of work you are doing in your worksheet.

Problem not auto-correcting spelling.
I have done the above steps in Excel 2013. - Ignore words in Uppercase is checked.
I can't get Excel to allow me to type HSA.

I have tried most obvious ways, Excel keeps correcting HSA to HAS.

Everything converts to HAS.

I guess it is time to go to 2016.
