If you have multiple sheets, you can remove a sheet or remove several sheets from the DataBook. There must always be at least one sheet in the DataBook.
Removing an existing sheet does not change the default sheet names provided to the other sheets. For example, a DataBook with three sheets would by default name them Sheet1, Sheet2, and Sheet3. If you remove the second sheet, the names for the remaining sheets are Sheet1 and Sheet3. You can also hide a sheet. For more information, refer to Showing or Hiding a Sheet.
