When you launch the Microsoft Excel Application, you would get three new blank sheets already. However if you still to open a new sheet in case of a need of a new sheet or in case you have closed the older sheet, you can do it by following the steps below:
Step (1): Use the Insert option by Right Clicking the Sheet Name.
Step (2): After clicking the Insert option, you will get the Insert dialog box as shown below. You have to select the Worksheet option, which is the first on the list, and click Ok button.
This will take you to the new blank sheet where you can start working as shown in the figure below.
The combination of Shift+F11 works as the shortcut keys for creating a new sheet just as we created in the steps above.
