Power Query Masterclass Advanced Data Cleaning & Automation

What you'll learn
Clean, transform, and automate Excel and Power BI data using Power Query to build efficient, repeatable workflows
Design scalable Power Query solutions that continue working reliably as data grows and changes
Understand Power Query data types (tables, lists, records) and retrieve values with clarity and confidence
Read, write, and modify M language to extend Power Query beyond basic transformations
Design queries that handle errors intentionally, resulting in more reliable and refresh-safe reports
Transform and automate complex real-world datasets, including multi-folder consolidation and unpivoted data
Adopt a modern analyst mindset focused on automation, scalability, and long-term maintainability
Build a clear and structured query architecture in Power Query so your solutions remain understandable and easy to manage
Requirements
Basic familiarity with Excel e.g. knowledge of pivotables, lookup functions, if statements is needed.
Description
Power Query is one of the most powerful tools available in Excel and Power BI for working with data at scale.It allows you to clean, transform, and automate data in a way that saves time, reduces manual effort, and creates solutions that can be reused again and again.This course is designed to help you build a clear and confident way of thinking about Power Query, so you can design data transformations intentionally and with purpose.Rather than focusing only on individual features, you'll learn how Power Query works as a system — how data flows through queries, how different data types behave, and how small design decisions affect long-term reliability.We start from the foundations and gradually move into more advanced, real-world scenarios, always explaining why each approach works, not just how to apply it.Throughout the course, you'll learn how to:Work confidently with tables, lists, and recordsUnderstand and edit M language in a practical, approachable wayDesign queries that adapt when source data changesHandle errors proactively to build reliable, refresh-safe solutionsTransform messy, real-world datasets that don't follow perfect structuresEverything is explained step by step, with a strong emphasis on clarity, logic, and scalability.What makes this course different is its focus on thinking and reasoning, not memorization. You'll learn how to approach Power Query problems methodically, design robust solutions before writing code, and build transformations that continue to work long after they're created.By the end of the course, Power Query will feel clear, logical, and under your control — allowing you to focus on higher-value analysis instead of repetitive data preparation.No prior Power Query or programming experience is required.If you want to work with data in a more scalable, automated, and intentional way, this course will change how you approach data transformation.
Who this course is for
Excel and Power BI users who want to build more automated, scalable, and reusable data workflows
Data analysts and business analysts who want to develop a deeper, more structured understanding of Power Query
Professionals who want their data transformations to remain reliable as source data grows and evolve
Learners who want clarity on how Power Query works, rather than just applying individual features in isolation
Anyone interested in moving beyond the Power Query interface and gaining confidence with M language
Students who value clear mental models, logical thinking, and well-structured solutions over memorizing steps
