Power BI Training (Jan 27, 2024) – Power Query, Data Cleaning & Modeling

This is a recorded Power BI training session from January 27, 2024, led by BMC Tutors. The focus is on the stuff that happens before you build any visuals—connecting to data, cleaning it up in Power Query, and getting your model ready for analysis. Practical, hands-on, and plenty of live troubleshooting. What's covered: ✅ Power BI Overview – A quick breakdown of the three main components: Power BI Desktop (building visuals), Power BI Service (cloud sharing/collaboration), and Power BI Mobile. ✅ Data Connection & Cleaning (Power Query) – Connecting to multiple data sources like CSV files, and using the Power Query Editor to clean and transform data. Covers removing unnecessary columns, replacing values, changing data types, splitting columns, and formatting text. Also explains the difference between Add Column vs. Transform when creating new data structures. ✅ Data Modeling & Management – Handling date formats and troubleshooting conversion errors. Using the Advanced Editor to copy transformation steps from one dataset to another—saves time when working with similar files. Also covers Append Queries to combine multiple years of sales data into one master table. Learning Highlights: Data cleaning comes before visuals. Always. Live troubleshooting of student issues—connection problems, system navigation, and more. Techniques for creating a consistent Calendar table and using Merge Queries to join data across tables (e.g., bringing price info into a sales table). Timestamps included – skip to what you need. 📞 Contact Us: 07039071675 📧 Email: [email protected] #PowerBI #PowerQuery #DataCleaning #DataModeling #BMCTutors #BusinessIntelligence #DataAnalytics #LearnPowerBI #PowerBITraining #BrattleMulticonceptsConsult
