How do you change the default number of sheets in a new Excel workbook?

Every time you open a new workbook in Microsoft Excel, by default, it opens with three worksheets. You can, of course, insert more sheets or delete ones that you don't need. The good news is the unused sheets don't occupy additional memory or increase your file size, but if you are like me, the extra sheets just annoy me for some reason. I like to keep my workbook nice and clean. What can be done about this?

Well, you can actually change the default value of the number of sheets the Excel automatically opens with. How do you do this?

For Excel 2003: Go to: Tools>Options and click General in the Options dialog box. Next, change the setting for "Sheets in new workbook". Now all new workbooks will have the number of sheets you specify. I typically change this number to one unless I know I am going to have a monster spreadsheet.

For Excel 2007: Select the office window button>Excel Options. On the popup menu you will see the section "when creating new workbooks." Change the "include this many sheets" from three to whatever you desire.
