You can programmatically create a worksheet and then add the worksheet to the collection of worksheets in the workbook.

To add a new worksheet to a workbook in a document-level customization

  1. Use the Add method of the Sheets collection.

    Excel.Worksheet newWorksheet;
newWorksheet = (Excel.Worksheet)Globals.ThisWorkbook.Worksheets.Add();

    Dim newWorksheet As Excel.Worksheet
newWorksheet = CType(Globals.ThisWorkbook.Worksheets.Add(), Excel.Worksheet)

    The new worksheet is a native Worksheet object and not a host item. If you want to add a Worksheet host item, you should add the worksheet at design time.

To add a new worksheet to a workbook in a VSTO Add-in

  1. Use the Add method of the Sheets collection.

    Excel.Worksheet newWorksheet;
newWorksheet = (Excel.Worksheet)this.Application.Worksheets.Add();

    Dim newWorksheet As Excel.Worksheet
newWorksheet = CType(Me.Application.Worksheets.Add(), Excel.Worksheet)

    The new worksheet is a native Worksheet object and not a host item. You can also generate a Worksheet host item from the native Worksheet object. For more information, see Extending Word Documents and Excel Workbooks in VSTO Add-ins at Run Time.
