Overview:

"Transforming Columns in Excel Power Query" is a comprehensive webinar designed to equip you with essential skills to handle various column transformations in Excel using Power Query. This session will delve into key techniques that will streamline your data manipulation processes and enhance your data analysis capabilities.

First, you'll learn how to format text columns to proper, uppercase, and lowercase formats, and ensure proper spacing using the Replace Values feature. Understanding the process of splitting text into columns using Power Query’s Split Column by Delimiter feature and how it differs from Excel’s Text to Columns will also be covered in detail. This will help you efficiently manage and organize textual data within your spreadsheets.

Next, you'll master the art of changing data types for columns, such as converting numbers to text or currency, to better suit the data’s purpose. We will also explore various ways to work with date columns, including extracting year, month, and day into separate columns. These skills will enable you to handle diverse data types and ensure your data is correctly formatted for analysis.

Creating custom columns using the M language for tasks like calculating ratios and winning percentages will be another focal point. Additionally, you will gain a clear understanding of the distinction between data types in Power Query and cell formatting in Excel, emphasizing how changes in Power Query affect data storage and not just the display formatting.

The webinar will also cover the differences and appropriate uses of calculated columns versus DAX measures, particularly in the context of data aggregation and pivot tables. This knowledge will empower you to choose the right approach for your data analysis needs, enhancing your efficiency and accuracy.

Finally, you'll learn techniques for reshaping data using the Unpivot feature to convert wide data into long format, facilitating more flexible data analysis options. By the end of this webinar, you'll be able to confidently transform your data to meet your analysis needs, ensuring accuracy and efficiency in your Excel workflows.
