Data Analysis with Excel and Power BI: Turning Raw Numbers into Actionable Strategy
Modern business decisions rely on data, but raw tables and fragmented spreadsheets rarely tell a story on their own. Data Analysis with Excel and Power BI is engineered to take you from foundational data hygiene to enterprise-grade business intelligence, teaching you how to clean, model, analyze, and communicate high-impact metrics with speed and precision.
What You Will Master
- Advanced Excel for Business Analytics: Go beyond simple formulas with multi-criteria lookups (
XLOOKUP,INDEX/MATCH), dynamic array functions, structured tables, and automated pivot tables for rapid ad-hoc reporting. - Data Cleansing with Power Query: Automate tedious ETL (Extract, Transform, Load) pipelines. Connect directly to multiple data sources, clean messy entries, handle null values, and unpivot data with zero manual repetitive work.
- Relational Data Modeling in Power BI: Move beyond flat sheets. Design robust star schemas, establish healthy table relationships, and manage data granularity to support scalable reporting environments.
- Business Calculations with DAX: Write expressive Data Analysis Expressions (
CALCULATE, time-intelligence functions, cumulative totals) to track complex corporate KPIs and year-over-year growth. - Executive Dashboards & Storytelling: Build interactive, cross-filtering dashboards that prioritize scannability and executive decision-making over visual clutter.
