Everyone's first Power BI report starts the same way: an Excel file that grew out of control.

In this session we take exactly that — a messy, real-world spreadsheet — and build a clean, interactive report live: importing and shaping data with Power Query, building a simple star schema (and why that one habit saves you months of pain later), writing your first measures, and choosing visuals that communicate instead of decorate. We'll finish by publishing and sharing the report properly.

Along the way I'll flag the beginner traps I see every week as a trainer — the "one big table" instinct, the calculated-column reflex, the pie chart temptation — and what to do instead.

Key takeaways:
1) Power Query basics and the star schema habit from day one.
2) Your first DAX measures, without fear.
3) The full example file and a report checklist to reuse on your next project.
