Pbi Power Query Basics in Power Bi
Power Query is the data transformation engine in Power BI that connects to diverse sources (Excel, SQL Server, APIs, web, cloud services) and cleans messy data. Every real-world dataset has issues: duplicate rows, missing values, inconsistent formatting, and irrelevant columns. Power Query solves this with a visual interface—no code required—by applying transformations step-by-step.
Common transformations include removing duplicates, filtering rows, renaming columns, splitting text (e.g., "John Doe" → "John" and "Doe"), changing data types (text to date), and merging tables. Each step is applied in sequence and can be undone, making experimentation safe. Power Query remembers all steps in the "Applied Steps" pane, so you can revisit and refine your cleaning logic.
Best practice: always apply transformations in Power Query rather than manually editing raw data. This ensures repeatability—when your data source updates daily, the same cleaning steps run automatically, eliminating manual work and errors.
