OmniDocEdit and Format a Table of Contents in Word on Mac
Learn how to edit table of contents entries and restyle them in Word on Mac, without losing changes when the table updates.
If you need to edit a table of contents in Word on Mac, you have probably already seen the problem. You fix a heading, and the old wording still shows in the contents. Or you bold one entry, and the formatting disappears after the next update. Word builds a table of contents from a field, so the way you make a change matters as much as the change itself.
This guide is for anyone who already has a table of contents in a Word document and needs to change its wording, its look or its page numbers. It does not cover inserting a table from scratch. You will learn which changes belong in the heading text, which belong in the style settings, and which ones you can make by hand without losing them.
The steps describe how Word for Mac works in general. If your file came from another editor or you only have a PDF copy, a later section covers those cases, including what the OmniDoc desktop client can and cannot do with a contents page.
How do you edit and format a table of contents in Word on Mac? The short answer
Fix the wording in the heading text in the body, change the look through the table's TOC styles, and then update the table so Word rebuilds it from your changes. Manual edits made inside the table are temporary.
| Your situation | What to do | Why |
|---|---|---|
| A heading's wording is wrong | Edit the heading in the body, then update the whole table | Entry text is copied from the heading, so the heading is the source to fix |
| You want every entry at one level to look different | Change the TOC 1 or TOC 2 style | One style change applies to all entries at that level |
| You need one entry to look different | Format it by hand, and expect the change to reset on update | Direct formatting inside the field is overwritten when the table updates |
| Page numbers look wrong after your edits | Update the table and choose to update page numbers | Page numbers depend on the current layout, so they must be recalculated |
| You only have a PDF copy | Edit paragraph text in the PDF editor, or re-export from the Word file | A PDF contents page has no live link to the headings |
Before you start
- Save a copy of the document. Each table update rewrites the field, and a copy lets you compare the before and after versions if an edit goes wrong.
- Confirm your headings use heading styles. Word only collects paragraphs that carry a heading style or outline level. Text that is bold and large but set to the Normal style will not appear in the table.
- Finish the content edits before you format. Adding or removing a paragraph can move entries to a different page, so format the table last to avoid redoing the styling.
- Turn on field shading if your Word version offers it. The shading shows where the table begins and ends, so you can tell generated text from ordinary body text.
- Check the file's history. If the document passed through another editor before reaching you, such as a web editor, open it and update the table once. This shows whether the table still works before you rely on it.
Editing and formatting a table of contents in Word on Mac, step by step
- Fix the heading text in the body. Find the heading in the document body and correct the wording there. The table copies heading text when it is built, so the body is where the change needs to happen.
- Use direct edits in the table only for a temporary fix. Click into an entry and type the new text if you need it right away. Word keeps the change until the table updates, then restores the text from the heading.
- Update the table. Right-click the table and choose the option to update the field. When you changed wording, choose the option that updates the entire table, not just page numbers, so the new text comes through.
- Open the styles pane and find the TOC styles. Look for the TOC 1 and TOC 2 entries, which control the first and second levels of the table. If you have more levels in use, their TOC styles work the same way.
- Modify the style, not the individual lines. Change the font, size, spacing before and after, or indent in the TOC style. Every entry at that level updates at once, and the setting survives later table updates.
- Set the tab leaders and page number alignment in the style. Dot leaders and right-aligned page numbers are part of the paragraph and tab settings for the TOC style. Setting them there keeps every line consistent.
- Update the table once more and check the result. Run the update again so the table reflects the style changes, then review the entries as described in the next section.
If you need to edit a contents page in a PDF instead, the OmniDoc desktop client includes a PDF editor that can edit paragraph text in place. The contents page in a PDF is printed text, though. Changing an entry there will not change its page number or any link to the heading, so fix the Word file and export it again when the content changes.
Check the result
Once the table has updated, check each item before you send or print the document.
| Check | How to see it | If it's wrong |
|---|---|---|
| Entry text matches the headings | Compare each entry with its heading in the body | Edit the heading in the body, then update the entire table |
| Page numbers point to the right pages | Scroll to a few entries and confirm the heading is on the listed page | Update the table and choose to update page numbers only |
| Every entry at one level uses the same style | Look at the TOC 1 and TOC 2 settings in the styles pane | Change the style itself instead of retyping each line |
| Your edits survived an update | Make a test change to one entry, update the table, and compare | If the change vanished, move it into the heading text |
| A PDF copy matches the Word file | Open the exported PDF and compare the entries and page numbers | Re-export the PDF after any change to the Word file |
Plan to check the table after every major edit, not only at the end. A table that looked correct at 20 pages can drift once you add a 3-page section near the front.
🎯 Which approach fits you?
Your approach depends on which part of the table you need to change.
- Wording changes: Edit the headings, then update the table. This is the right method for almost every correction.
- Visual changes to all entries: Modify the TOC styles. This keeps the look consistent and survives updates.
- One-off visual changes: Format a single entry by hand only if it is a final document that will not be updated again.
- PDF-only workflows: Make small text corrections in the PDF editor, and return to the Word file for anything that affects page numbers.
❓ FAQ
1. Why is a heading missing from my table of contents?
Word only collects paragraphs that use a heading style or have an outline level. A heading formatted to look like a title but set to the Normal style will be skipped. Apply a heading style to that paragraph, then update the table.
2. How do I stop one heading from appearing in the table?
Change that paragraph's style to a non-heading style, such as Normal, and then update the table. The paragraph stays in the document, but it drops out of the contents.
3. Can I edit a table of contents in a PDF with the OmniDoc desktop client?
Yes, the PDF editor can change paragraph text in place. The page numbers and any links stay as they were, though, so a PDF edit is only a quick fix. Make permanent changes in the Word file and export again.
4. Will my table still update if I open the file in the UniDoc web editor?
UniDoc's web editor supports Word-compatible editing, but the product facts do not say how it handles table fields. Open the file, update the table once, and check the entries and page numbers before you rely on the result.
📝 Summary
Editing a table of contents in Word on Mac works well when you treat the table as generated output. Fix headings in the body, change the look through the TOC styles, and update the table after each round of edits. Check entries and page numbers before you share the file, and re-export any PDF copy after the Word file changes.
