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.

Excel : Closing a Workbook

If you’re no longer working with a workbook , you may want to close the workbook so that you can work on other documents without distraction. Closing unneeded workbooks also frees memory and minimizes potential screen clutter. To close the unneeded workbook or workbooks, follow these steps:

1. If multiple workbooks are open, ensure that the workbook you want to close is active as follows: Click the View tab on the Ribbon, click the Switch Windows button, and select the workbook from the list of names in the menu.
2. Use any of the following methods to close the workbook:
   • Click the Office button and then choose Close.
   • Click the Close button on the far right of the Ribbon tab area (or on the workbook’s title bar if the workbook is not maximized).
   • Double-click the Control button on the far left of the workbook’s title bar if the workbook is not maximized.
   • Press Ctrl+F4.
   • Press Ctrl+W.
   If you’ve made any changes to your workbook since the last time you saved it,Excel asks whether you want to save the changes before closing the workbook.
