Question details

The user is unable to generate a table of contents in Microsoft Word for Mac, even though heading styles appear to have been applied to the text.

Product: Microsoft Word for Mac
Device & OS: macOS
Scenario: Creating a structured table of contents based on applied heading styles.
Observed behavior: The table of contents is not created, or it fails to recognize the customized heading styles applied within the document.

Before you start

Verify whether the text in your document is formatted with Word's default built-in heading styles (Heading 1 through 9) or if you are using custom-created styles.

Solution 1Recommended

Use Built-in Heading Styles

The most reliable way to ensure your Table of Contents generates correctly on Mac is by utilizing Word's default built-in heading styles.

The desktop application for Word on Mac automatically includes Heading 1 through Heading 3 in the Table of Contents by default.

Select text

Highlight the text in your document that you want to serve as a section heading.

Apply built-in style

Navigate to the Home tab on the ribbon and click on the Styles Pane. Select a default built-in style such as 'Heading 1', 'Heading 2', or 'Heading 3'.

Insert Table of Contents

Go to the References tab, click on 'Table of Contents', and select an automatic style to generate your table.

Solution 2

Assign TOC Levels to Custom Heading Styles

If you prefer using custom heading styles, you must manually assign a table-of-contents level to each custom style so Word knows to include them.

Solution 3

Test Heading Styles in a New Document

Creating a new document helps determine if the issue is isolated to a corrupted file or a broader application problem.

Frequently Asked Questions

Why does my table of contents say 'No table of contents entries found' on Mac?

This error occurs because Word cannot detect any text formatted with the designated heading styles. You must either apply built-in styles (Heading 1, 2, 3) to your text or manually map your custom styles to TOC levels in the Table of Contents options.

How do I include Heading 4 and below in my Word for Mac Table of Contents?

By default, the desktop app only includes up to Heading 3. To include deeper levels, go to References > Table of Contents > Custom Table of Contents, and change the 'Show levels' setting to 4 or higher.

Can I use the Word web application to fix table of contents issues?

Yes, the Word web application automatically includes all heading levels 1 through 9 that are used in the document. Opening your file in the web app might bypass local desktop configuration glitches.
