Power Query is a data preparation and transformation tool from Microsoft that helps users import, clean, reshape, and combine data from different sources. It provides a visual interface, so many common data preparation tasks can be completed without writing code.

Power Query is integrated into products such as Excel and Power BI, allowing users to create repeatable data workflows. Once transformation steps are defined, they can be applied again whenever the source data is refreshed.

How Power Query Works

  • Connect: Select a data source such as an Excel file, CSV, database, web page, or SharePoint location.
  • Import: Load the selected data into the Power Query Editor for preparation.
  • Transform: Clean and reshape the data by filtering rows, changing data types, splitting columns, removing duplicates, and performing other transformations.
  • Combine: Merge or append multiple tables and datasets when information needs to be joined or consolidated.
  • Automate: Power Query records transformation steps so the same process can be repeated automatically when data is refreshed.
  • Load: Send the transformed dataset to Excel or Power BI for reporting, analysis, and visualization.
