What is the function of the query editor in Power BI?

• A. To visualize data relationships
• B. To clean, reshape, and transform data prior to loading it into the Power BI model
• C. To create dashboards directly from the data
• D. To set up user permissions for report sharing

Answer: (B)

The function of the query editor in Power BI is primarily to clean, reshape, and transform data before it is loaded into the Power BI model. This capability is essential for preparing data for analysis and visualization. The query editor allows users to perform various operations such as filtering rows, changing data types, merging tables, and adding calculated columns. This preprocessing ensures that the data model is accurate, relevant, and organized, which enhances the quality of any visualizations and insights derived from it. Using the query editor effectively enables users to tailor the data to meet specific analytic needs, ensuring a better experience when the data is ultimately used in reports and dashboards. By transforming and cleansing the data in this way, users can address data quality issues, remove unnecessary data, and streamline the data structure for more efficient analytical workflows.
