With the standard versions of Microsoft® Office, you cannot view and edit multiple files within a single tabbed window.
Office Tab changes this by introducing a tabbed user interface - as seen in web browsers such as Internet Explorer® 8, Firefox and Google Chrome - in Microsoft Office 2016, 2013, 2010, 2007, 2003 and Office 365 (Word, Excel®, PowerPoint®, Publisher®, Access®, Project and Visio®).
Features include:
    - Open, read, edit, and manage multiple Office documents in a single tabbed window.
    - Minimize the number of windows you open at the same time.
    - Save and close all Office documents with one click.
    - Based on Microsoft Office add-in technology.
Verdict:
An essential add-in for anyone who finds themselves working with multiple Word, Excel or PowerPoint documents on a regular basis.
