With the Office document you want to preview displayed onscreen, open the File menu and select Web Page Preview.
The document is opened in your computer's default Web browser. Click the Close (x) button in the browser window to exit and return to the original Office document.
INTRODUCTION
Office enables you to convert the documents you create using various Office applications into Web pages. At any time, you can view the documents you save as Web pages to see how they look.
TIP
Browser Buttons and Links
Notice that the Web browser acts just like it is displaying an active Web page. The document name is in the title bar, and the Explorer bar buttons are active.
TIP
Online Comments
If you have comments in a document that you publish to a Web page, you can move the mouse pointer over the comment indicator (the red bracket in the upper-right corner of the cell) to display the comment in a ScreenTip.
