I'm completely new to Matlab and am not sure as to the best way to import data onto Matlab. I'm looking at 'Coronavirus Pandemic Cases by Country' and only need data of cases from: Australia, China, Italy, the United States, Brazil, and Zambia.
The document is a .xlsx file.

You could do it this way:
1- Copy all the data and paste them in a file and maybe call it data.txt
2- Make sure the data.txt file is in your matlab path
3- try these basic lines to call your columns
load 'data.txt';
A=data(:,1); %calling column A -- Number 1 means that A is the 1st column
B=data(:,2); %calling column D -- Number 2 means that B is the 2nd column
