How can I check that the worksheet SheetNo I want to read from really exists? I'm referencing it by xlBook.Worksheets(SheetNo) but I cant always be sure of the number of sheets in the Excel file.

Thanks.

Hi mawe,

Use the function below to test if a WorkSheet is exist

Private appExcel As Excel.Application
Private wbExcel As Excel.Workbook
Private WSheet As Excel.Worksheet

Set appExcel = CreateObject("Excel.Application")
Set wbExcel = appExcel.Workbooks.Open(txtPath.Text)

If DoesSheetExist("123") Then
'Exist
Else
'Does Not Exist
End If

and here is the Function:

Private Function DoesSheetExist(SheetName As String) As Boolean
    On Error Resume Next
    DoesSheetExist = wbExcel.Sheets(SheetName).Name = SheetName
End Function

Hope this help

-----------------------------------------------------------

Private appExcel As Excel.Application

Private WSheet As Excel.Worksheet

Private SheetNumber As Long
Private SheetName As String

Private Sub Command1_Click()
Set appExcel = CreateObject("Excel.Application")
Set wbExcel = appExcel.Workbooks.Open("C:\test.xls")

' To Test
SheetName = "Tabelle1"
SheetNumber = 1

' Test1: name ?
For Each WSheet In appExcel.Worksheets
If WSheet.Name = SheetName Then MsgBox ("Worksheet exists")

mawe, what's wrong? According with your question, both comments could do the job?, why "B" grade?
