  • Parameters and Functions in Power BI / Power Query–Combine Files Experience

    Combine Files

    I highly recommend that you read the first and second part in this series prior to reading this one, but you can jump right in if you understand the main concepts of parameters, arguments and functions in the M language.

    Understanding the Combine Files Experience: Practical Example


    The scenario that we’re going to tackle is going to be THE most common way that people use Functions without even knowing what is going on.

    We’ll go over the new Combine Files experience that was introduced in Power BI Desktop at the start of 2017 and how everything changed from there.

  • Parameters and Functions in Power BI / Power Query–Custom Functions


    Power Query has over 600 native functions and the Power Query team keeps adding more and more.

    I wouldn’t recommend memorizing them, but you do need to understand the concept of parameters and arguments in order to understand what functions are.

    In this blog post I’ll go over what Custom Functions are and how you can create them. Be sure to check out Part 1 of this series before reading this one.

  • Merge Operations in Power BI / Power Query – Part 6: Full Outer Join


    This is the last post in the series! I highly encourage you to read Part 5 of this series before reading this one, but nevertheless, you can jump right in if you know the basics of Merge / Join Operations inside of Power BI / Power Query.

    We will be using the same sample data that we used in Part 5, but this time we’ll have a completely new goal which is probably one of the most frequent ones that I’ve had when Modelling data for Power BI.

    In this, Part 6, we’ll go over the Full Outer Join from a purely practical standpoint.

  • Merge Operations in Power BI / Power Query – Part 4: Right Anti Join


    Similar to the previous posts in this series, I highly encourage you to read the first 3 Parts ( 1 | 2 | 3 ) that I’ve published so far around Merge / Joins inside of Power BI / Power Query.

    So far I’ve covered:

    • Left Outer Join
    • Right Outer Join
    • Left Anti Join

    In this, Part 4, we’ll go over the Right Anti Join from a purely practical standpoint.

  • Merge Operations in Power BI / Power Query – Part 1: Left Outer Join

    If you’ve used Power Query or Power BI before, you’ve probably seen the “Merge” button which displays a window like the following:


    and this let’s you join 2 tables (or queries), and one of the questions that I get pretty often is: “What’s up with all of those ‘Join Kinds’ ? when should I choose which one?”

    and that’s why I’m writing this series of blog posts around this specific topic from a purely practical standpoint so you can get a glimpse of what each one of those merge operations can bring to the table.

    In this, Part 1, we’ll start with the default join which is the Left Outer Join.
