POWER QUERY: DATA CLEANING AND AUTOMATION IN EXCEL
ETL Practical Guide for Beginners Do you spend hours copying, pasting, and correcting Excel files every week? Discover Microsoft's "secret engine" that will automate your work for good.
In today's professional environment, data is the most valuable asset. However, the reality for most professionals is frustrating: 80% of the time is wasted on repetitive tasks before they can start analyzing. Correcting broken formats, consolidating files from different folders, crossing endless sheets of data with heavy formulas, and dealing with annoying date or text errors consumes hours that you should spend making strategic decisions.

You don't need to be a programmer, database expert, or master complex code. This book will guide you in a clear and structured way through the ETL (Extract, Transform, and Load) methodology so that you can build efficient workflows that update automatically.
