One of the biggest reasons that business leaders love Power BI is because it can handle large volumes of data. If you are used to reporting in Excel, consider the following: a lot of computers would have difficulties opening a CSV file that is 300MB. This really limits you as far as what you can do in Excel. PowerBI, on the other hand, can compress all of your excel, text and CSV files and visualize large quantities of data that Excel simply cannot compete with. In fact, all of your files can be stored connected and analyzed while taking up about 50MB.
Power BI can be integrated with other tools offered by Microsoft such as SharePoint, Dynamics 365 and Office 365. It can also be used with non-Microsoft products such as Salesforce, Google Analytics, SAP and many more. If you are looking to analyze all of the data in your CRM to identify new business opportunities, trends and make predictions. Among other Microsoft PowerBI benefits, it has a very intuitive interface that can be easier to use than Excel, or anything else that you are using for analysis.
