Referring back to Figure 1, below the Title Bar is the Ribbon. Users who are familiar with modern versions of Microsoft Office will recognize the function of this area, although the controls displayed will be somewhat different.

The ribbon consists of four permanent tabs and three contextual tabs. The permanent tabs are as follows:

• File: The File tab actually displays a fly-out menu when clicked that allows overall file operations, such as opening and saving Power BI Desktop files. Power BI Desktop files have the .pbix file extension. Other operations include importing data, exporting, and publishing.
• Home: The Home tab provides a variety of the most common operations, such as copying and pasting, getting data, inserting visuals, creating calculations, and other common actions. 
• Modeling: The Modeling tab provides operations common to the data modeling process, including creating calculations, sorting, formatting, and categorizing data columns, as well as operations related to security, grouping, and Q&A.
• Help: The Help tab includes useful links for getting help with Power BI, including links to the Power BI Community site, documentation, guided learning, and training videos.

The three contextual tabs are only available when in the Report view. These tabs are as follows:

• View: The View tab provides operations that control page size, formatting functions such as enabling grids, and snap objects to grid and lock objects, as well as the ability to activate additional panes.
• Format: The Format tab is all about formatting how visuals interact with one another or are displayed in relation to one another.
• Drill/Data: The Drill/Data tab provides operations focused on Power BI's ability to drill into data and see the raw data that makes up a visualization.

The first tab becomes active immediately when in Report view, while the other two appear when a visual is selected. These last two tabs appear under the heading, Visual Tools.
