Profiling the Data
Troubleshooting in Power Query
In this course, we’ll review the Power BI Desktop interface. Then, we’ll show you how to load data into Power BI Desktop and how to save your file. We will also explain data profiling and look at the various data profiling options in Power Query like column quality, column value distribution and column profiling, and the benefits of using these.
Lastly, we will look at how to resolve cell-level errors, empties, and inconsistencies in Power Query. This section will cover how to replace errors, replace values, remove rows, and how to identify the root cause of the error using Power Query. The demos in this course will provide you with practical examples that will help you to troubleshoot when encountering issues while loading data into Power BI.

This is the Power BI Desktop Interface. At the top is the ribbon. And you can see that this resembles the Office ribbon, you might be familiar with through use in other software programs. Below this, on the navigator pane, you can see the Get data button. This is the starting point and what you select to load data into Power BI.
On the left, you have the View selector with three viewing options, report view, data view, and model view.
To the right, you can see the field section. Tables and fields will be reflected here, once data is loaded into Power BI. Next to that, you can see all the data visualization options. We will spend more time understanding all the views and options as we move further through the course. Lastly, in the top left corner is the Save file button.
