How to unpivot data in Power Query, then use this as a basis for a pivot table

This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.

Before you can do this exercise, you'll need to download and unzip this file.

In a new Excel workbook, choose to import data from the workbook in the above folder:

Creating a new query

Choose to import data as above.

Initially you have your work cut out:

Raw data

There's a fair amount to do!

In Power Query choose to skip a row, and also to use the next one as column headers to get this:

Tidied up data

Time now to unpivot this data ...

Select the decade columns, and choose to unpivot them to get:

Unpivoted data

You don't need the grand total any more, so delete the Grand Total column.

Rename columns as above, and filter the data to show only those countries and decades in which at least 5 films were made:

Final table

You should now have 43 rows.

You'll also thank yourself for changing the data type of the final column from Any to Number at this point, so that you can sum it later.

Load this data into PowerPivot, and create a pivot table based upon it like this:

Start of pivot table

The first 3 rows of the final pivot table.

Take a moment to wonder what you've achieved (!), then save this workbook as Repivot.xlsx.

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
