What is Power Query?

Power Query is a data transformation and preparation tool that allows you to import, transform, and combine data from various sources. It is available in both Excel and Power BI and offers a user-friendly interface for data manipulation. With Power Query, you can easily clean, reshape, and merge data to create comprehensive datasets for analysis.

What is Power BI?

Power BI is a business analytics tool that enables you to visualize and share insights from your data. It provides a comprehensive suite of tools for data modeling, analysis, and visualization. Power BI integrates with Power Query, allowing you to leverage the data preparation capabilities of Power Query to create powerful visualizations and reports.

The Difference between Power Query and Power BI

The main difference between Power Query and Power BI lies in their primary functions. Power Query focuses on data transformation and preparation, while Power BI is designed for data analysis and visualization. Power Query provides a user-friendly interface for cleaning, reshaping, and merging data, whereas Power BI offers a wide range of visualization options and advanced analytics features.

While Power Query is available in both Excel and Power BI, the Power Query user interface may vary slightly between the two tools. In Excel, Power Query is integrated into the Data tab of the ribbon, while in Power BI, it is accessed through the Transform Data button in the Home tab.
