Open the Document in the Desktop Word Application

Since Word for the web has limited reference controls, you must open the document in the full desktop version of Word to access the Table of Contents update feature.

Word for the web offers a streamlined editing experience but lacks advanced formatting tools, including the ability to automatically refresh fields like a table of contents. To properly update your automatic summary, you will need to open the file in a fully-featured desktop word processor.

Open in Desktop App

While viewing your document in Word for the web, click the 'Editing' or 'Viewing' button on the top ribbon menu, then select 'Open in Desktop App'.

Navigate to References

Once the document opens in your desktop Microsoft Word application, click on the 'References' tab located at the top of the window.

Update Table

Click the 'Update Table' button in the Table of Contents group. A prompt will appear asking if you want to update page numbers only or the entire table. Choose your preferred option and click 'OK'.

Open the Document in the Desktop Word Application

Version Requirement: This solution requires you to have the full desktop version of Microsoft Word installed on your Windows or Mac computer.

Frequently Asked Questions

Why doesn't my table of contents update automatically in Word for the web?

Word for the web is a simplified version of the desktop application designed for basic editing. It does not support automatic field updates for references like the table of contents, meaning you have to use a desktop word processor to refresh the page numbers.

Do I have to recreate the table of contents if I switch to the desktop version?

No. The desktop application will recognize the automatic table of contents created in the web version. You simply need to navigate to the References tab and click the 'Update Table' button to refresh the existing fields.

Can I update page numbers if I don't have a desktop Microsoft 365 subscription?

Yes. You can download your document as a .docx file and open it in a free alternative desktop application like WPS Office, which fully supports updating table of contents fields and page numbering without requiring a subscription.
