After you create a workbook, you can begin entering data. The simplest way to enter data is to click a cell and type a value. This method works very well when you’re entering a few pieces of data, but it is less than ideal when you’re entering long sequences or series of values. For example, Craig Dewar, the VP of Marketing for Consolidated Messenger, might want to create a worksheet listing the monthly program savings that large customers can realize if they sign exclusive delivery contracts with Consolidated Messenger. To record those numbers, he would need to create a worksheet tracking each customer’s monthly program savings.
