Power Query is a free add-in created by Microsoft for Excel 2010 (or later) and you can download and install it for Excel 2010 and 2013:
In Excel 2016 it comes built in the Ribbon menu under the Data tab and within the Get & Transform group.
Power Query allows you to extract data from any source, clean and transform the data and then load it to another sheet within Excel, Power Pivot or the Power BI Designer canvas.
One of the best features is to Unpivot Columns.
What that does is transforms columns with similar characteristics (e.g. Jan, Feb, March…) and puts them in a unique column or tabular format (e.g. Month), which then allows you to do further analysis using Pivot Tables which was not possible before unpivoting.
Here is how this is done:
STEP 1: Highlight your data and go to Power Query > From Table > OK
STEP 2: This opens the Power Query editor and from here you need to select the columns that you want to unpivot
STEP 3: You then need to go to the Transform tab and select Unpivot Columns
STEP 4: Go to the File tab and choose Close & Load
STEP 5: This will load and open the unpivoted data into a new worksheet with your Excel workbook. Now you can go crazy with your super analytical work, using Pivot Tables etc
