Use Query Editor to import and tidy up a list of the richest people

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.

Create a new Power BI report, and load in the data in the above workbook:

Richest people

The raw data - your task is to massage it into something more presentable!

Use Query Editor to make this data look better:

Query Editor results

Some columns have been renamed, while each person's wealth (in billions of dollars) has been extracted - see below for how.

If you need hints on extracting the wealth of each person in billions, one way to proceed is to follow these steps:

Step	What to do
1	Replace the word billion with an empty string.
2	Replace the $ symbol with an empty string.
3	Convert the resulting column to a whole number.

Bring the data back into your Power BI report, and use it to create a simple chart:

Pie chart

Create a simple chart just to prove that the billions really are being treated as numbers.

Save this report as But are they happy, then close it down.

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