One of the more tedious tasks in Analytics is preparing data for analysis. Power BI offers a powerful tool for loading and transforming data called Power Query or, simply, Query Editor. Power Query is also available in Excel as ‘Get and Transform’, the default mechanism to load external data in Excel 2016 and later versions. Moreover, the same techniques can be used in SQL Server Analysis Services, Azure Analysis Services, and in the Dataflows component of the Power BI cloud service. If you can work in Power BI with this tool, you can reuse your knowledge in the other tools as well!

Power Query is a data preparation technology, connecting data sources and analytical models. It is the new standard for transforming source data into a workable format. When properly used, your analytical models will perform better and can be easier maintained. In this two-day course, you will not only learn how to work with Power Query but to apply best practices as well, to get the most of the technology.
