Power Query M Language Essentials for Data Transformation

Unlocking the full potential of data transformation often requires going beyond standard graphical interfaces. Learning the M language in Power Query gives you direct control over custom data manipulation, data reshaping, and automated workflow logic. This foundational course guides you through core syntax, essential functions, and structured coding patterns in M. You will start by understanding basic data types and structures, then progress to writing custom formulas and handling errors gracefully to streamline your data pipelines across Power Query, Excel, and Power BI. What you will learn: Understand core M language terminology, primitive data types, and evaluation rules. Construct structured data objects including primitive values, lists, records, and tables. Write custom M functions to automate repetitive data cleaning steps. Apply conditional logic alongside built-in text, list, and table functions. Implement robust error handling patterns using try and otherwise expressions. Practice writing clean, readable M script blocks for scalable data queries. The material begins with essential definitions and syntax mechanics before introducing practical code construction. Through detailed written explanations and code examples, you will build confidence in writing and troubleshooting M code manually. Designed specifically for beginners and data professionals looking to master M code fundamentals without prior programming experience.
