You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
In a new Excel workbook, choose to import data from the workbook in the above folder:
Choose to import data as above.
Initially you have your work cut out:
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:
Time now to unpivot this data ...
Select the decade columns, and choose to unpivot them to get:
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:
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:
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.
