A Microsoft Excel workbook is a file that contains one or more worksheets (worksheet: The primary document that you use in Excel to store and work with data. Also called a spreadsheet. A worksheet consists of cells that are organized into columns and rows; a worksheet is always stored in a workbook.), which you can use to organize various kinds of related information. To create a new workbook, you can open a blank workbook. You can also base a new workbook on an existing workbook, the default workbook template (default workbook template: The Book.xlt template that you create to change the default format of new workbooks. Excel uses the template to create a blank workbook when you start Excel or create a new workbook without specifying a template.), or any other template (template: A workbook that you create and use as the basis for other similar workbooks. You can create templates for workbooks and worksheets. The default template for workbooks is called Book.xlt. The default template for worksheets is called Sheet.xlt.).
