My Experience with Power Query
I’ve been using Power Query for several years, and it has been an invaluable tool in my data preparation workflow. One of the aspects I appreciate the most is its intuitive interface, which allows me to perform complex transformations without needing to write extensive code.
For instance, I often need to clean and combine data from multiple sources. Power Query makes this process straightforward with its Merge and Append features. Additionally, the ability to create custom functions has saved me a significant amount of time by automating repetitive tasks.
Another feature I find particularly useful is the robust error handling. When working with large datasets, it’s common to encounter inconsistencies or errors. Power Query helps me quickly identify and resolve these issues, ensuring the data is accurate and reliable.
The seamless integration with Excel and Power BI is another highlight. I can easily import data into Excel for further analysis or visualize it in Power BI, making the entire data preparation and analysis process more efficient. Another advantage is that both, Excel and Power BI, work with the Power Query engine. So, if you are already familiar with Excel, the transition to Power BI will be smoother compared to a transition to alteryx.

Alteryx workflow example
Personally, I enjoy doing ETL work with alteryx as I can instantly see the output. be it true or false or the outcome of a left join, inner join or right join. In Power BI the applied steps only show the selected outcome but not the data rows which were filtered out. This makes quality control much easier with alteryx.
The image below shows a inner joint (J) of two datasets in alteryx. If you want to switch to a left (L) join or right join (R) simply select the green output anchor and connect it with the next action. Simple, easy to switch and possible to compare multiple outcomes.
