Types of Data Transformations In Power BI

• Filtering Rows: This transformation helps you remove data that doesn’t meet certain criteria, such as excluding records with null values or data outside a specific date range.
• Sorting Data: Organize your dataset by sorting it in ascending or descending order based on one or more columns. This is useful for ranking products, sales figures, or other metrics to highlight top performers or trends.
• Grouping Data: Aggregate data into categories or groups to summarize and analyze it more effectively. For instance, you can group sales data by region or product category to see the total sales figures for each group.
• Merging Queries: Combine data from different tables or sources into a single dataset. This allows you to integrate related information, such as merging customer details with sales data, to get a comprehensive view for analysis.

4 Ways to Transform Power BI Data

1. Power Query Editor: Use Power Query Editor to perform a wide range of data transformations, such as filtering, sorting, and merging tables. This tool provides a user-friendly interface for shaping and cleaning data before loading it into Power BI.
