Excel, among the Office applications, is still the 800-pound gorilla in spreadsheets. It's possible to name your spreadsheet everything you want. Once you've published your spreadsheet, make a new graph or edit existing one and see the second step, which gives you the ability to upload your CSV file. For tracking sales commissions it's usually simpler to use a spreadsheet particularly if you have several sales commissions each sale. The genuine spreadsheet is still personal, obviously. You can also track down the spreadsheet in your Drive.
