Table of contents

A table of contents gives readers a map of a longer document such as a thesis, report, or proposal, listing each section heading and the page where it begins. In Microsoft Word the reliable way to build one is not to type it by hand but to let Word generate it automatically. Word scans the document for text formatted with built-in heading styles (Heading 1, Heading 2, Heading 3, and so on) and assembles them into a live, clickable TOC with correct page numbers; when you add, remove, or move content you simply right-click and choose Update Field to refresh it. This only works if your headings actually use those heading styles rather than being manually bolded or enlarged, which is a common reason an auto-generated TOC comes out empty or wrong. That makes consistent heading styling the real prerequisite for a working table of contents. A formatting tool that applies proper Heading 1/2/3 styles across a document restores the structure Word needs to build and maintain an accurate TOC.
