Data transformation is the foundation of every modern analytics workflow — and Power Query M is the engine that makes it happen. Whether you’re working in Excel, Power BI, or Microsoft Dataflows, this book gives you the knowledge and confidence to master the M language from the ground up.

In Learning Power Query M, you’ll go beyond point-and-click interfaces and learn to write clean, efficient, and reusable M scripts that unlock deeper automation, richer insights, and more flexible data models.

What You’ll Learn

• Power Query Fundamentals – Understand the architecture, connectors, and data flow behind Power Query.
• M Language Syntax – Learn variables, functions, lists, records, and table operations through real examples.
• Transformations in Action – Combine, filter, and reshape data from multiple sources with precision.
• Automation & Parameters – Build dynamic solutions using query parameters and custom functions.
• Error Handling & Debugging – Use try...otherwise, conditional logic, and diagnostics tools to build reliable queries.
• Performance Optimization – Learn best practices for improving refresh time and efficiency.
• Integration with Power BI & Excel – Apply your M skills directly within the tools you already use.

Why This Book Stands Out

• Code-Driven Learning – Every concept includes examples you can run immediately.
• Real-World Scenarios – Based on practical business data challenges.
• Reusable Templates – Includes ready-made scripts for cleaning, merging, and aggregating data.
• Professional Focus – Ideal for analysts, BI developers, and Excel power users seeking deeper automation skills.

Who This Book Is For

• Data Analysts looking to automate and scale their transformations.
• Excel Users ready to move beyond formulas and macros.
• Power BI Professionals aiming to improve model efficiency and governance.
• Students & Educators seeking a clear, structured introduction to Power Query M.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
