Free online courseExcel and Power BI Data Analysis Fundamentals (Excel, Power Query, PivotTables, DAX)

Course Description

Stop guessing with spreadsheets and start making confident, data-driven decisions. This free online course builds a practical foundation in data analysis using the tools employers expect: Excel, Power Query, PivotTables, Power Pivot, DAX, and Power BI Desktop. You will learn how to move from raw files to reliable insights by treating your data as something that can be refreshed, updated, and reused, rather than manually rebuilt each time numbers change.

In Excel, you will strengthen core analysis habits that make every workbook easier to maintain: organizing information as proper data sets, converting ranges into Excel Tables for cleaner references, and applying logical tests to validate and enrich your data. From there, you will see when classic formulas shine and when modern dynamic arrays can speed up analysis and reduce repetitive work. You will also develop intuition about choosing the right approach for a given question, whether that means a formula-driven report that stays fully customizable or a PivotTable that summarizes large data quickly.

As the course progresses, you will shift into transformation and modeling, which is where analytics becomes scalable. Power Query helps you import, clean, and shape data consistently so you can refresh the same steps whenever new files arrive. You will learn how to decide between lookup-based methods and true data modeling techniques, especially when you are combining multiple tables or working with large datasets. That modeling mindset prepares you for Power Pivot and DAX, where measures make analysis more powerful, reusable, and accurate across different views and filters.

Finally, you will connect these skills to Power BI Desktop, focusing on how to structure models that stay dependable as your data grows. By the end, you will be able to build a refresh-friendly workflow from Excel sources, create meaningful summaries, and communicate results through clear tables, charts, and formatting that highlight trends and patterns. If you want a solid entry point into business intelligence and office productivity with real-world tools, this course provides a focused path from fundamentals to job-ready analysis habits.
