## The challenge 🤺

We run a coffee shop and have downloaded this month’s sales data from a third-party system into Excel. We want to analyze this data in a Pivot Table and quickly see the total sales for each coffee type by coffee size.

However, the data is a bit of a mess.

It’s our job to tidy up this data in Power Query and then create a Pivot Table to show this analysis.

Currently, the data has a few problems:

• All fields are in one column.
• There is a row that needs to be deleted.
• There are erroneous spaces throughout the data that need to be removed.
• The data in the columns is not formatted correctly.

We can tidy up this data and fix these issues using Power Query

Some points to think about before you begin:

1. Make a note of the delimiter that separates each field.
2. Think about how you might remove spaces in the data and the header row.
3. Remember to load the data back into Excel as an Excel table.

Once the data is clean and loaded into Excel, we can analyze it with a Pivot Table

Ensure the Pivot Table has the following properties:

• Perform an analysis to show the Total Sales by Product
• Apply a dark orange Pivot Table style that has banded rows toggled on.
• Apply Accounting number format with two decimal places.
• Add a Slicer to filter the data by Size.
• Format the slicer so that the sizes run horizontally instead of vertically.
• Position the slicer above the Pivot Table.
• Apply a dark orange slicer style.
• Add a Calculated Field to the Pivot Table that calculates the total with 20% tax added.
• Sort the Pivot Table data from largest to smallest.

If you’re just getting started with Excel, all the knowledge you need to solve this challenge has been shown in the above videos.

If you’re already proficient with Excel, this should be pretty easy. Maybe you can tell us a creative way to solve this problem in our Slack channel.
