How many blank worksheet(s) are shown, by default when a new workbook is created?

3

In Excel, a file is referred to as a "Workbook." Within a workbook, you can find multiple "Worksheets". By default, three sheets, named Sheet 1, Sheet 2, and Sheet 3, are provided for users. At any given moment, only one worksheet can be designated as the "Active Worksheet," which is the sheet available for users to perform operations on. You can identify the active worksheet by its name displayed in bold letters on the "Sheet Tab" located at the bottom left of the screen.
