Hey there! Hello!
In an instance of Microsoft Excel 2016, you can select your entire worksheet by using the Ctrl-A shortcut on your keyboard for Windows, or Command-A in the case of a Mac. If you have a standard Windows keyboard, you should have two Ctrl keys on either side of your keyboard. On a standard Mac keyboard, you'll also find that there are two Command keys on either side of your space key. This shortcut applies to other things as well, such as documents in Word. It basically selects everything there is to select.
I have attached a screenshot of the result of doing Command-A on a blank document. Everything within the bolded green outline is selected – it's typical for the cell you were on to be white instead of your highlight color (which is grey, in my case), and it will be selected, too.
Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)
