“A journey of a thousand miles begins with a single step.” – Lao Tzu

If you’re serious about learning Power BI, follow this step-by-step roadmap to become an expert.

Step 1: Understand the Basics

📌 Learn the Power BI Interface – Get comfortable with menus, ribbons, and panels.
📌 Explore Data Sources – Learn how to connect Power BI to Excel, databases, and APIs.

Try This: Open Power BI and import a simple Excel sheet to create your first report!

Step 2: Data Transformation with Power Query

📌 Clean Data Like a Pro – Remove duplicates, format columns, and fill in missing data.
📌 Merge & Append Data – Combine multiple data sources for a comprehensive analysis.
