    This is going to be the last post series in the series on Combine or Append Data.

    In the first post we saw the basics of how to do the Append operation through the UI.

    In the second post we saw the Combine Files experience with Flat Files and how easy it is to combine as many files as you want.

    In the third post we had a contrast of the Combine Files experience using Excel Workbooks instead of simple flat files and what things we needed to consider this time that we didn’t consider with simple flat files.

    In this fourth and last post we’ll be going back to the basics using the function that we discovered in the first post – Table.Combine which is the most optimal function for combining / appending data.

    In the previous post we saw how we were able to combine multiple files from a Folder.

    In that post we were using flat files but, how would that process be for Excel files?

    This is the post where we’re going to see the difference between simple flat files and more complex files (like an Excel workbook) when it comes to using the Combine Files experience inside of Power BI / Power Query.

    Combine Flat FIles from Folder

    In the previous blog post, I went through the basic concepts behind the Append operation found in Power Query for Excel and Power BI.

    In that post, we only used 2 files and it was pretty straightforward to simply click the Append queries button to combine both queries like so:

    A more complex scenario

    but what happens when you have multiple files? Let’s say 12 files. 1 for each month of the year.

    I’ve previously done a series on Merge / JOIN operations (First Part here) and it’s now time to do one on Combine / Append operations.

    so…How do you combine / append / stack tables with Power BI / Power Query?

    There are multiple ways to accomplish this, but we’re going to start with the basics.

    I’ve been trying to join multiple Facebook communities that revolve around Power BI topics.

    I was able to join a couple communities that are completely neutral in the sense that they’re not run by a for-profit company, but rather just community members which make things easier as there’s little chance of a conflict of interest with the admins of the group.

    One of these groups is called “Power BI Latinoamerica” which is a Community that primarily speaks the Spanish language and within that group one of the admins posted a video that caught my attention:

    It’s basically a video that showcases a way to connect to an Excel file that is being hosted on OneDrive and while that method is completely valid, I was trying to reference the author of that video to one of my articles about connecting to files hosted on SharePoint and OneDrive and then I realized that I haven’t formally wrote about that topic in my blog…ever.

    Disclaimer, I’ve created multiple videos about this for some of my online courses, so you might’ve seen this method before if you’ve followed any of the courses where I participate.

    It’s time to change that! Let’s find out what’s the easiest and most optimal way to connect to ANY file hosted on OneDrive or SharePoint.

    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.

    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.
