What is Power Query?
Power Query is a powerful data transformation and preparation engine designed to simplify the process of getting data from various sources and applying necessary transformations. With its user-friendly graphical interface, Power Query allows users to perform extract, transform, and load (ETL) operations efficiently.
How Power Query Helps with Data Acquisition
Business users often spend up to 80% of their time on data preparation, which can delay analysis and decision-making. Power Query addresses several challenges in this area:
| Existing Challenge | How Does Power Query Help? |
|---|---|
| Finding and connecting to data is too difficult | Power Query enables connectivity to a wide range of data sources, accommodating data of all sizes and shapes. |
| Experiences for data connectivity are too fragmented | It offers a consistent experience and parity of query capabilities across all data sources. |
| Data often needs to be reshaped before consumption | The interactive interface allows for rapid and iterative query building over any data source. |
| Any shaping is one-off and not repeatable | Users can define repeatable processes (queries) that can be easily refreshed for up-to-date data. |
| Volume, velocity, and variety of data | Power Query allows users to work against a subset of the entire dataset to define required transformations. |
Power Query Experiences
Power Query is available through two primary experiences:
- Power Query Online - Found in integrations like Power BI dataflows and Azure Data Factory.
- Power Query for Desktop - Available in applications such as Power Query for Excel and Power BI Desktop.
User-Friendly Interface
The Power Query Editor provides a user-friendly interface where users can connect to various data sources and apply hundreds of transformations by simply selecting options from the UI. Power Query automatically generates the necessary M code behind the scenes, so users don’t need to write code manually.
Transformations
Power Query includes numerous prebuilt transformation functions, ranging from simple tasks like removing columns to advanced options such as merging and grouping data. Users can easily apply these transformations through the graphical interface.
Power Query M Formula Language
For advanced transformations that require special configurations, Power Query uses the M formula language. Users can access the Advanced Editor to modify the script of their queries as needed.
Where Can You Use Power Query?
Power Query can be found in various Microsoft products and services, including:
- Excel for Windows/Mac
- Power BI
- Power Apps
- Azure Data Factory
Conclusion
Power Query is an essential tool for anyone dealing with data preparation and transformation, offering a seamless experience across multiple platforms. Whether you're a business analyst or a data scientist, Power Query can significantly enhance your data handling capabilities.
