I have written about profiling data and the importance of it in Power Query, I also explained how the profiling data can be prepared to create a report in Power BI for the user to understand the data better. And I explained how the error count of that can be added to the report. Another Read more about Creating Column Values Distribution Report in Power BI Using Power Query[…]
Does Power Query requires training or reading a book, or even reading an article? I get this question a lot from those who started Power BI not long ago. Many users think that Power Query is just the get data from the source, and that’s it. Considering the many data source connectors in the Power Read more about Why data preparation and transformation? Why Power Query?[…]
I have written two articles about fuzzy operations in Power BI and Power Query so far; fuzzy matching in Power BI, and fuzzy grouping. the methods above involve transforming the data with a fuzzy operation. However, sometimes you just want to know the similarity of values, or let’s say in other words; find the clusters.

An essential step towards a better analytics solution is to know your data. You have to know your data to be able to determine key columns, to learn what transformations need to be done, and etc. Power Query provides a very useful way of knowing your data in Power BI. Power BI has features for Read more about Know Your Data Better by Column Profiling In Power BI using Power Query[…]
I have explained previously what fuzzy matching in Power BI is and how to use it. In this article and video, I’ll explain Fuzzy grouping. Fuzzy grouping in short means grouping text values by their similarity based on a threshold, rather than exact equal values. This option at the moment is available in Power Query Read more about Fuzzy Grouping in Power BI using Power Query[…]
Age banding is a common scenario in analytics, and I have explained how it is possible in many different ways. One of the methods I have explained was using DAX measures and the TREATAS function. Sometimes, however, the age banding can be static, and Power Query can be used for the calculation, which would make Read more about Age Banding in Power BI using Power Query – Merge Queries Based on Between[…]
When applying text transformations in Power BI using Power Query; two very important transformations that can help are; Trim and Clean. These two mistakenly often considered to do one thing, but they are different. In this short article and video, I’ll explain their differences through an example. Video Sample text Let’s assume I have a Read more about Trim Vs. Clean in Power BI and Power Query[…]
There are many useful transformations in Power Query for Power BI. One of them is adding the prefix and suffix to a text column. These transformations are very simple to apply and have an immense value in building columns based on patterns and template texts. In this short video and article, I’ll explain how you Read more about Add Prefix and Suffix to a Text in Power BI: Generate Country Images and pages[…]
Power BI has the built-in feature of creating binning for a numeric field such as age. However, the default binning will create bins of equal size. If you want to create bins of different sizes, then you need to create that as a custom column. Fortunately, Power Query has transformations that can help. In this Read more about Create Customized Age Bins (or Groups) in Power BI[…]
When you have blank values in your data table, you can use Power Query transformations to remove the row with blank values. There are two transformations that are used very often for this purpose: Remove Empty and Remove blank rows. These two transformations are not exactly the same. In this article, I’ll explain what is Read more about Row Filtering in Power BI and Power Query: Remove Blank Rows Vs. Remove Empty[…]
