This one-hour course will focus on the use of Excel with Power BI and Power Query to organize and analyze data. Users will primarily work with calculated columns generated from existing data. They will walk through hands-on exercises to create calculated columns, add dimensions to existing data tables, and create hierarchies within the data tables.
