More Spelling Options in PowerPoint 2016 for Windows

While it is indeed easy to spell check your entire presentation for any misspelled words, there are other options that you need to be aware of that will help to check your slides for spelling errors. Here are some tips to help you understand how you can do better proofing of your text content in PowerPoint 2016 for Windows:

1. Whenever PowerPoint encounters a spelling error, it highlights the misspelled word by placing a red squiggly line to underline the word, as shown highlighted in red within Figure 1.
2.

3. Now, right-click the word that's underlined with the red squiggly line. Doing so brings up a contextual menu that offers one or more suggestions to replace the wrong word, as shown highlighted in red within Figure 2. To accept any of these suggestions, just click on the relevant suggestion. PowerPoint then replaces the misspelled word with the suggested word you chose.

Ignore All and Add to Dictionary

5. In addition, you will also find the options at the bottom of this contextual menu (highlighted in blue within Figure 2, above):

Ignore All

6. The option ignores spell check for this word in your entire presentation, but only during this spell-check operation. If you shut down PowerPoint, reopen this presentation, and do another spell-check, then the Ignore All choice will have to be chosen again.

Add to Dictionary

7. Using the option, you can quickly add this word to PowerPoint's spelling dictionary. You will never be prompted to correct this spelling again. Do note that PowerPoint shares the same dictionary with other Microsoft Office programs such as Word, Outlook and Excel. And, those programs will also consider the new spelling as acceptable.
2. PowerPoint's spell checker does not check for spelling errors in charts and any other inserted objects. Even with PowerPoint 2016, which relies on fewer inserted objects, charts are actually an instance of Microsoft Excel working behind the scenes. And PowerPoint only spell checks content that is part of PowerPoint.
3. Fortunately PowerPoint does spell check any text within text placeholders and text boxes on your slides. It also looks for spelling errors in text contained within tables, SmartArt, slide notes, and shapes. Remember though, that you must always manually check all spellings within charts!
3. Remember that everything on your PowerPoint slide is larger than life. A spelling error within a 20 page Word document may go unnoticed but the same misspelled word in 44 pt. size as a title of your PowerPoint slide will attract a disproportionate amount of attention, making the slide and the presenter look unprofessional. Make sure you spell check all your slide content before you present!
