Excel, among the Office applications, is still the 800-pound gorilla in spreadsheets. It is possible to name your spreadsheet whatever you want. As soon as you've published your spreadsheet, make a new chart or edit existing one and visit the next step, which gives you the capability to upload your CSV file. For monitoring sales commissions it's usually simpler to use a spreadsheet particularly if you have several sales commissions each sale. The real spreadsheet remains private, naturally. You could even locate the spreadsheet on your Drive.
