Index in MS Word

Last Updated : 6 Apr, 2026

An index is a list of important terms or topics with their corresponding page numbers, usually placed at the end of a document. In Microsoft Word, entries can be marked manually or generated automatically, and the index can be updated dynamically.

Key Features

  • Dynamic Updates: The index updates only when you refresh fields (F9 or Update Field).
  • Customizable Entries: Include main entries, subentries, and cross-references to related terms.
  • Flexible Formatting: Customize the index’s appearance, such as column layout or font style.
  • Navigational Aid: Helps readers find information quickly in long documents.

Example: Create an index in a technical manual listing terms like “installation” and “troubleshooting” with page references.
