We repeat this process for the 2018 file and then we’ll end up with 2 queries: This is pretty simple and in our case our csv files have the correct format thus not requiring any transformation steps to be done to it other than the ones that were automatically done by Power BI / Power Query. To finish things off, you can just click on Edit so we can go straight to the Power Query Editor. This is a pretty straightforward process where we can just select our data source from the “Get Data” window and go through the import process which will display a simple browse window so you can select your file and then give you a preview of your data like this:

It can be 1 CSV and 1 Excel file, maybe 1 table from a database and another one from an API. There are multiple ways to accomplish this, but we’re going to start with the basics.
