If worksheets are the basic building blocks used to store information in Microsoft Excel, workbooks are the organizational tools you can use to manage data effectively. By default, each Excel workbook contains three worksheets. In this chapter, you'll learn how to switch between worksheets, name worksheets, add worksheets to a workbook, delete unwanted worksheets from a workbook, and rearrange worksheets. You'll also learn how to work with more than one workbook at once, how to link information between worksheets and workbooks, how to create and manage shared workbooks on a network, and how to protect worksheets and workbooks by using password protection. When you're finished, you'll have all the tools you need to manage workbooks effectively.
