Excel : Creating an Empty Workbook

After you start Excel, it automatically creates a new (empty) workbook that it calls Book1. If you’re starting a new project from scratch, you can use this blank workbook.
You can create another blank workbook in the following ways:

1. Press Ctrl+N.
2. Click the Office button, choose New, select Blank Workbook, and click Create.

You can add a button to the Quick Access toolbar that allows you to create a blank workbook with a single mouse click. Click the arrow to the right of the Quick Access toolbar and choose New from the menu. Excel adds the New button to the toolbar.
