978-1-4842-9753-7 (ISBN)
The Ultimate Guide to Functions in Power Query begins with an introduction to Power Query and an overview of the different types of functions available, along with detailed explanations of how to use each of them. You’ll see how to leverage power functions to process and transform large datasets from various sources and learn advanced techniques such as creating custom functions and using conditional statements. The book also covers best practices for using functions, including tips on how to optimize query performance and troubleshoot common errors. Using practical example applications, Author Omid Motamedisedeh demonstrates how to optimize your data processing workflows, saving time and boosting productivity.
By the end of the book, readers will have a deep understanding of Power Query functions and be ableto apply their knowledge to a wide range of data analysis tasks.

Who This Book Is For
Anyone who wants to learn how to use functions in Power Query to transform and analyze data. This includes data analysts, business analysts, Excel users, and data scientists. Readers should have a basic understanding of Excel and data analysis concepts, but may be new to Power Query and functions.
Omid Motamedisedeh is a freelance data and business intelligence analyst with a PhD in Industrial Engineering. He’s currently working towards his second PhD at Queensland University of Technology. Omid has authored six books in the field of Excel in Farsi, along with several articles in industry journals (Electric Power Systems Research, Journal of Building Engineering, Energy, Neural Computing and Applications, and more). His primary reason for writing his first book in English is the lack of a comprehensive and complete reference for Power Query functions. He decided to fill this gap by writing one himself.
