A workbook is an Excel file that holds entered related information. The data included on each worksheet usually labels workbooks. Each workbook contains three worksheets, and the worksheet is a page in each workbook. Each page is filled with a certain amount of data.
A worksheet is comprised of data that can be manipulated to design charts, graphs, or arrays that visually project the primary goal of the data that was originally entered. The worksheet is what shows what the workbook entails.
Without the worksheets, the workbook would be empty. A workbook cannot necessarily be manipulated. The manipulation of data is directly through worksheets.
