When spell checker is not working in Word, it can lead to unnecessary stress, especially when working on an important document, but fear not! We have several solutions featured below that will get you back to working with documents, stress-free.
Fix 1. Use Google Docs to Check the Spelling
A quick workaround if you’re having trouble with Microsoft Word is to use Google Docs, which is free. This method will allow you to upload your Word document to your Google Drive, open it in Google Docs, use its built-in spell checker, and download the document as a Microsoft Word file again.

Next, click ‘Tools’ at the top of your screen, followed by ‘Spelling and grammar’ and finally ‘Spelling and grammar check’, alternatively, you can use the keyboard shortcut ‘Ctrl+Alt+X’.

Fix 2. Choosing Proofing Language
Microsoft Word's spell checker will not function properly if your proofing language is incorrectly set. Word might be checking for spellings in a language that doesn’t match the one your document is written in.
Checking the Proofing Language Settings in Microsoft Word
Click ‘Review’ at the top of your screen, then click the dropdown arrow underneath ‘Language’ and select ‘Set Proofing Language.’ In this new window, ensure the language chosen matches your document. Lastly, ensure the ‘Do not check spelling or grammar’ box is not selected, and click ‘Ok’.

Fix 3. Enable Check Spelling as You Type
The check spelling as you type option automatically highlights spelling mistakes as you work. If this option is disabled, Microsoft Word won’t check spelling in real-time, making it look like the spell checker isn’t working.
Enabling Check Spelling as You Type
Click ‘File’ at the top left of your screen, followed by ‘Options’. In the window that opens, select ‘Proofing’ from the list on the left. Lastly, find the option ‘Check spelling as you type’ and ensure the box is checked.

Fix 4. Disable Hide Spelling Errors in This Document Only
Another reason you might not be able to see the spelling errors in your Word document is the ‘Hide spelling errors in this document only’ option. When enabled, this can prevent Word from showing any spelling errors, even if the spell checker is functioning.
Disabling the Hide Spelling Errors in This Document Only Setting
Click ‘File’, followed by ‘Options’, and ‘Proofing’. In this window, you’ll likely have to scroll down to find the ‘Hide spelling errors in this document only’ option, ensure it is unchecked, and click ‘Ok’.

Fix 5. Repair Word
If none of the fixes above resolved the complication with the spell checker, the issue could be due to file corruption in Microsoft Word. Repairing your installation of Microsoft Word may fix the problem.
Repairing Microsoft Word
Open the Control Panel on your computer, click ‘Programs and Features’, scroll down to find ‘Microsoft Word’ in the list of installed programs, right-click and select ‘Repair’, and follow the on-screen prompts.
Fix 6. Disable Conflicting Add-ins
Sometimes, Add-ins can conflict with Word’s spell checker, causing it to malfunction. These add-ins may override Word’s built-in features, and if you suspect this to be the cause, disabling them can resolve your difficulties.
Disabling Add-ins
Click ‘File’ followed by ‘Options’, and select' Add-ins' in the new window that opens. Click ' Go ' next to the ‘Manage COM Add-ins’ section. In this window, uncheck the add-ins for the grammar checking, for example, Grammarly.
