How to Fix a Corrupted or Incorrect Table of Contents in Microsoft Word

Product: Microsoft Word
Device & OS: not provided
Scenario: Generating, updating, or formatting a document's Table of Contents.
Observed behavior: The Table of Contents appears corrupted, displays incorrect headings, or glitches due to automatic content controls, leading the user to consider typing the entries manually.

Before you start

Ensure all your document headings are properly styled using Word's built-in Heading styles (Heading 1, Heading 2, etc.), as the Table of Contents relies strictly on these styles to generate accurate structure.

Solution 1Recommended

Verify Heading Styles and Update the TOC Field

Applying built-in heading styles consistently and updating the TOC field is the most common fix for incorrect or missing entries.

A Table of Contents is generated dynamically based on the text formatted with Heading styles. If normal paragraph text appears in your TOC, or if headings are missing, the styles in the document body need to be corrected before updating.

Apply correct heading styles

Scroll through your document, highlight the text that should appear in your TOC, and apply the appropriate built-in style (e.g., Heading 1 or Heading 2) from the Styles gallery on the Home tab.

Remove styles from regular text

If regular paragraph text is showing up in the TOC, highlight that text in your document and click 'Normal' in the Styles gallery to remove the heading formatting.

Update the field

Scroll back up to your Table of Contents, right-click anywhere inside the table, and select 'Update Field'.

Update the entire table

If prompted, choose 'Update entire table' rather than just page numbers, then click 'OK'.

Verify Heading Styles and Update the TOC Field

Formatting Retained: Updating the entire table ensures all your newly applied heading styles are captured accurately without requiring you to delete and recreate the TOC.

Solution 2

Insert a Custom Table of Contents

Automatic tables use content controls that can sometimes cause formatting glitches; inserting a custom TOC provides more stability and control.

Frequently Asked Questions

Why does my Word Table of Contents say 'Error! Bookmark not defined.'?

This error occurs when a heading referenced in the Table of Contents has been deleted, altered, or its invisible bookmark was removed. To fix it, simply right-click anywhere in the Table of Contents and select 'Update Field' > 'Update entire table'.

Can I manually edit the text inside an automatic Table of Contents?

While Word allows you to type directly into the Table of Contents, any manual edits you make there will be permanently lost the next time the TOC field is updated. It is highly recommended to edit the actual heading text within the body of your document, and then update the TOC field.

How do I change the font and spacing of my Table of Contents?

To permanently change the formatting, go to References > Table of Contents > Custom Table of Contents. Click the 'Modify' button, select the TOC level (TOC 1, TOC 2, etc.) you want to change, and click 'Modify' again to adjust the font and paragraph spacing. This ensures the formatting persists even after updates.
