This course teaches students how to prepare and manage data using Power Query through a structured, step-by-step approach. Participants will learn to apply data transformations, reorganize datasets with pivoting and reshaping tools, and combine information from multiple files and tables.
The course also emphasizes building summarized views with grouping and conditional logic, creating new columns from examples, and maintaining organized queries through duplication, applied steps, dependencies, and data refresh processes.
What You Will Learn
- Navigate the Power Query interface, understand the data analysis process, and work with Power Query options, applied steps, and refresh behavior.
- Clean and transform data by filtering rows, removing and reordering columns, changing data types, splitting and merging columns, and applying text cleanup techniques.
- Create structured transformations using grouping, conditional columns, date and duration calculations, and columns generated from examples.
- Reshape datasets using Pivot, Unpivot, Transpose, and split-to-rows techniques to support analysis and reporting.
- Combine data from multiple sources by appending tables, worksheets, and CSV files, and merging data using inner and anti joins.
- Organize and manage queries by duplicating and referencing queries, handling errors and values, removing duplicates and blank rows, and working with query dependencies.
