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 billions 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.
