You have data. A lot of it. And right now, it is probably living in one giant, beautiful, chaotic flat Excel file that somehow holds everything together. If your reports feel slow, your visuals feel wrong, or your data just refuses to behave the way you want it to in Power BI, you are not imagining things and you are definitely not alone.

In this hands-on, roll-up-your-sleeves workshop, we will take that flat Excel file and transform it into a clean, efficient star schema that Power BI absolutely loves. You will learn how to think like a data modeler, identify your facts and dimensions, and restructure your data so your reports are faster, smarter, and so much easier to build. With Power Query doing the heavy lifting and Copilot lending a hand, you will walk away with a model that is ready for the real world and the skills to build the next one on your own.

Key Takeaways:
- Understand the difference between a flat file and a star schema and why it matters for your Power BI reports
- Identify fact tables and dimension tables in your own data and learn how they work together
- Use Power Query to reshape, clean, and split flat Excel data into a proper data model
- Build relationships between tables and see the immediate impact on your report performance and flexibility
- Apply data modeling best practices that scale with your organization's needs

If you have ever stared at a Power BI report that refused to do what you wanted, the problem was probably upstream in your data model. Join this workshop and learn how to fix it at the source, so every report you build from here on out is faster, cleaner, and finally doing exactly what you need it to do. Bring your laptop, bring your curiosity, and get ready to go from flat to fabulous!
