Any data analytics solution requires data population and preparation. With the rise of data analytics solutions these years, the need for this data preparation becomes even more essential. Power BI is a helpful data analytics tool that is used worldwide by many users. As a Power BI (or Microsoft BI) developer, it is essential to learn how to prepare the data in the right shape and format needed. You need to learn how to clean the data and build it in a structure that can be modeled easily and used high performant for visualization. Data preparation and transformation is the backend work. If you consider building a BI system as going to a restaurant and ordering food. The visualization is the food you see on the table nicely presented. The quality, the taste, and everything else come from the hard work in the kitchen. The part that you don’t see or the backend in the world of Power BI is Power Query. You may already be familiar with other data preparation and transformation technologies, such as T-SQL, SSIS, Azure Data Factory, Informatica, etc. Power Query is a data transformation engine capable of preparing the data in the format you need. The good news is that to learn Power Query; you don’t need to know programming. Power Query is for citizen data engineers. However, this doesn’t mean that Power Query is not capable of performing advanced transformation. Power Query exists in many Microsoft tools and services such as Power BI, Excel, Dataflows, Power Automate, Azure Data Factory, etc. Through the years, this engine became more powerful. These days, we can say this is essential learning for anyone who wants to do data analysis with Microsoft technology to learn Power Query and master it. We have been working with Power Query since the very early release of that in 2013, named Data Explorer, and wrote blog articles and published videos about it. The number of articles we published under this subject easily exceeds hundreds. Through those articles, some of the fundamentals and key learnings of Power Query are explained. We thought it is good to compile some of them in a book series. A good analytics solution combines a good data model, good data preparation, and good analytics and calculations. Reza has written another book about the Basics of modeling in Power BI and a book on Power BI DAX Simplified. This book is covering the data preparation and transformations aspects of it. This book series is for you if you are building a Power BI solution. Even if you are just visualizing the data, preparation and transformations are an essential part of analytics. You do need to have the cleaned and prepared data ready before visualizing it. This book is compiled into a series of two books, which will be followed by a third book later; Getting started with Power Query in Power BI and Excel (already available to be purchased separately) Mastering Power Query in Power BI and Excel (This book) Power Query dataflows (will be published later) This book deeps dive into real-world challenges of data transformation. It starts with combining data sources and continues with aggregations and fuzzy operations. The book covers advanced usage of Power Query in scenarios such as error handling and exception reports, custom functions and parameters, advanced analytics, and some helpful table and list functions. The book continues with some performance tuning tips and it also explains the Power Query formula language (M) and the structure of it and how to use it in practical solutions. Although this book is written for Power BI and all the examples are presented using the Power BI. However, the examples can be easily applied to Excel, Dataflows, and other tools and services using Power Query.

Welcome another lesson in the Mastering Excel series. This lesson is a slight departure from previous lessons. This lesson is looking into the future and delving into what Excel is becoming: a powerhouse for data analysis. Power Query is the first step in analyzing data, before you do any substantial analysis, you need to get the data into Excel. Not only get data into Excel but probably clean it up. Parse columns, join columns, remove errors, you know, that kind of stuff.Of course, you can add a column with formulas to do this. That will work for 100 or 1,000 rows of data. What about 250,000, 700,000 or even 1,000,000 rows? Excel really slows down with that many calculations. Power Query solves this. It shapes the data before it gets into Excel. You will learn how to use Power query to split columns, parse data, check for errors, get data from multiple files in a folder, and more. Power Query remembers all the steps you took. To get new data, you simply have to click the 'Refresh' button.***OK, THIS IS IMPORTANT***Power Query is a new feature in Excel. It is standard in Excel 2016 and it can be installed in some previous versions of Excel, but not all. Before buying this lesson, please go to this Microsoft website, check out the requirements and try to install Power Query.https://www.microsoft.com/en-us/download/details.aspx'id=39379If you cannot install Power Query because you do not have the correct version of Excel, you will not be able to follow along with this lesson.
