Fix SharePoint 2019 Spell Checker Not Working for Multi-line Text

Product: SharePoint Server 2019
Device & OS: not provided
Scenario: Attempting to correct spelling errors using the built-in spell checker in a multiple-lines-of-text field that contains several paragraphs.
Observed behavior: The spell checker successfully corrects text in single-line fields but fails to replace misspelled words when using Change Once or Change All in multi-paragraph content fields.

Before you start

Before troubleshooting, verify your exact SharePoint Server 2019 build number and ensure your web browser is fully up to date, as rich-text spell check behaviors can sometimes be affected by browser compatibility.

Report the Issue to the Microsoft Q&A Community

Since this is a known behavioral issue specific to SharePoint Server 2019, reaching out to Microsoft experts is the most effective way to find a patch or official workaround.

SharePoint Server 2019 handles rich-text and multi-line fields differently than single-line inputs. When standard features like 'Change All' fail to execute the text replacement script in these specific fields, it often requires a server-level cumulative update or patch from Microsoft.

Frequently Asked Questions

Why does the SharePoint spell checker work for single-line text but not multi-line text?

In SharePoint Server 2019, the text editor handles multi-paragraph (multiple-lines-of-text) fields using complex HTML and rich-text configurations. This differing architecture can sometimes break the JavaScript executing the 'Change Once' and 'Change All' functions, unlike the simpler plain-text single-line fields.

Can I use my web browser's built-in spell checker instead of SharePoint's?

Yes. You can often bypass the SharePoint rich-text spell checker by relying on your modern web browser's native spell checker (such as Google Chrome or Microsoft Edge) to highlight and correct misspelled words directly within the text fields.

Is there a patch available for this SharePoint 2019 spell checker bug?

Microsoft periodically releases cumulative updates (CUs) for SharePoint Server 2019. Check the Microsoft Q&A community or the official Microsoft Update Catalog to see if a recent patch addresses this specific multi-line text spell check limitation.
