Excel, among the Office applications, is still the 800-pound gorilla in spreadsheets. It is possible to name your spreadsheet whatever you want. Once you've published your spreadsheet, make a new graph or edit existing one and see the next step, which gives you the capability to upload your CSV file. To start with, you have to prepare the spreadsheet in Google Apps. 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 private, naturally. You can also locate the spreadsheet in your Drive.
