The Ribbon runs along the top of the application window and is the replacement for the menus and toolbars that were commonplace in previous versions of Microsoft Excel. The Ribbon has several tabs and each tab has its own groups of commands. The HOME tab is where the most common Excel formatting takes place, such as changing fonts, paragraph alignment, and line spacing. But if, for example, you wanted to insert a graphic or table into your document, you would click on the INSERT tab.
