solutions – data transformation
Power Query makes data transformation simple, repeatable, and powerful by offering a graphical interface that requires a minimum of coding, so users can clean and reshape data with ease.
Here, we have valid data, but it is provided in an unfortunate format as there are 3 lines of data in every single record which makes analysing, displaying and comprehending the data difficult, if not impossible:
| Date: 05/04/2026 Item: Apple Amount: 5 |
| Date: 11/8/2026 Item: Pear Amount: 3 |
| Date: 7/7/2026 Item: Banana Amount: 7 |
We can transform this data with Powerquery to a more usable format that will also handle added, changed or deleted data.
Once a transformation workflow is set up, it can be fully automated and refreshed with a single click, eliminating tedious manual rework every time the source data changes.
| Date | Item | Amount |
| 05/04/2026 | Apple | 5 |
| 11/08/2026 | Pear | 3 |
| 07/07/2026 | Banana | 7 |
Power Query connects to dozens of data sources including Excel files, databases, web APIs, and cloud services, while keeping original source files completely untouched because all transformations happen in memory.
It provides built-in cleaning tools to remove duplicates, split columns, handle missing values, pivot and unpivot data, and merge queries.
Power Query integrates seamlessly with Excel, Power BI, and Microsoft Fabric, loading results directly into data models or dashboards. In short, Power Query turns messy, repetitive data preparation into an automated, transparent, and scalable process that saves hours of work and reduces errors.
