Creating a new workbook
On starting Excel 2007 you will be presented with a new blank workbook named Book1. The new workbook will contain 3 sheets identified by the sheet tabs in the bottom left of the worksheet.
To create a new blank workbook, click the Office Button > New > Create or press Ctrl + N.
It is recommended to customise the Quick Access Toolbar to include the New workbook icon to make creating blank workbooks easier in future.
Every time a new blank workbook is created it is named Book1, Book2, Book3 and so on until saved under a more appropriate name.
Excel 2007 also provide a variety of templates to use when creating new workbooks. To use one of these templates click the Office Button > New.
Click Installed Templates for a list of pre-installed templates, My templates to access any you may have created, or pick one from the categories of templates under Microsoft Office Online.
There are lots to choose from which can help get you started or provide you with some useful ideas.
