How do I open the Worksheet (Excel File)
If you have Microsoft Excel, you can open the Worksheet directly from the program.
If you do not have Microsoft Excel, you can use a Free Google Account and open it from Google Sheets.
To do that you must first have a Free Google Account. If you do not have an account, then you can signup here: https://accounts.google.com/SignUp
Once you are logged into your Google Account, you can open up your Worksheet by following these instructions:
Go to the Google Sheets Home.
Then hit the Open file picker icon in the top-right corner.
Convert Excel To Google Sheets - Open Picker
Next, hit the Upload tab and drag your XLS file into the Upload section or hit Select a file from your computer and choose the Excel file you want to upload.

Your file will then be uploaded and converted to Google Sheets and you can open your Worksheet file.
