"What is the Office Web Viewer?
It's a service that creates Office Web Viewer links.  Office Web Viewer links open Word, PowerPoint or Excel files in the browser that would otherwise be downloaded. You can easily turn a download link into an Office Web Viewer link to use in your website or blog (e.g., recipes, photo slide show, a menu, or a budget template).
Some benefits of the Office Web Viewer include:

• You don't need to convert Office files for the web (e.g., PDF, HTML).
• Anyone can view Office files from your website or blog, even if they don't have Office.
• It keeps eyes on your website or blog, because readers don't need to download the file and they stay in the browser.
• One link will work for computers, tablets, and mobile phones."
