Power Query is an Excel feature available within the newest versions of Excel. It used to be an add-in feature called Power Query. Microsoft calls it Power Query as well as Get and Transform and it is a business intelligence tool that allows you to retrieve data from a variety of sources, clean it and then transform or refine the data as needed. For example, you can import a database file, parse data, split or combine columns, change data types, group data and more. You can then take that transformed data back into Excel and analyze it using your preferred methods. What makes this feature exciting is that Excel records all your steps so the data in the file can automatically be refreshed with Excel retrieving the source data, applying the same steps and updating the file for you. This is a huge time saver and will also reduce errors.

Version: **This feature is only available in Excel versions starting with Excel 2016 but not all 2016 versions have it ** To, see if you have this feature, simply click on the Data tab in Excel. You should see a section of the ribbon called Get & Transform. If you do not see this section, then you do not have the Get & Transform Data feature and will not be able to do any of the exercises in this eBook. If you have the older add-in feature called Power Query you should be able to follow along just fine.

This is my first time taking a text based course, but this is a very helpful and informative course. Text based content walked me through the major tips of using power query functions in my own pace. This is really great method to learn a hands-on tool. But the only drawback might be that the last exercise in the Unpivot section was not very clear. My data could not be successfully loaded to Excel for some reason that the text did not mention even though I followed the same steps. I spent a whole afternoon working on this course, which is more than the expected 2 hours.

This is an informative course. It helps lay out the Power Query steps easier and explains the logic behind certain steps. I thought the questions about joins seemed to be switched (right/left) for the answers. Not sure - perhaps the wording is just strange.
