First, a spreadsheet is not printed as it is created, but as you enter data, your spreadsheet software displays it on the screen. Your spreadsheet can be printed later. This allows you make many changes to your spreadsheet without using even one piece of paper.

Second, you can easily edit or modify your data. This includes moving numbers around in your spreadsheet, deleting, inserting, and replacing data. Since only the parts that need editing are retyped, you are spared retyping the entire spreadsheet. This will decrease the amount of time you spend retyping.
