How many blank worksheets are shown when a new workbook is created?

Three

A file in Excel is known as a “Workbook”. A workbook is a collection of a number of “Worksheets”. By default, three sheets, namely Sheet 1, Sheet 2, and Sheet 3 are available to users. At a time, only one worksheet can be made as “Active Worksheet” and that worksheet is available to a user for carrying out operations. An active worksheet’s name will be shown in bold letters in the “Sheet Tab” at the bottom left of the screen. Additional sheets can be added, if required, by clicking on the icon (which works as Insert ! Worksheet !).
