When you create a new spreadsheet in Excel, it includes a single worksheet by default. To do the setup:
Open Microsoft Excel.
Click the File tab, then click Options.
Ensure the General screen is active on the Excel Options dialogue box.
Go to the When creating new workbooks section and enter the number of worksheets (three or more) in the Include these many sheets box. You can also click the up and down arrows on the box to increase or decrease the number.
Click OK to save the change and close the Excel Options dialogue box.
When you create a new workbook, it will have the number of worksheets you specified.
