Although you're limited to 255 sheets in a new workbook, Excel doesn't limit how many worksheets you can add after you've created a workbook. The only factor that ultimately limits the number of worksheets your workbook can hold is your computer's memory.

A Range is a group of selected Cells in an Excel worksheet. A Range can be rectangular or square in shape. You can select a Range by left-click, drag and release the mouse over the cells you want to select. ... Similarly, a Range in Excel worksheet is identified by a Range Address.
