Test or check if sheet exists

Question

Dim destsheet As Worksheet

For Each ThisWorkSheet In wkbkorigin.Worksheets 
    \'this throws subscript out of range if there is not         


        

Answer 1

I did another thing: delete a sheet only if it's exists - not to get an error if it doesn't:

Excel.DisplayAlerts = False 
Dim WS
For Each WS In Excel.Worksheets
    If WS.name = "Sheet2" Then
        Excel.sheets("Sheet2").Delete
        Exit For
    End If
Next
Excel.DisplayAlerts = True

Answer 2

Short and clean:

Function IsSheet(n$) As Boolean
    IsSheet = Not IsError(Evaluate(n & "!a1"))
End Function

Answer 3

I actually had a simple way to check if the sheet exists and then execute some instruction:

In my case I wanted to delete the sheet and then recreated the same sheet with the same name but the code was interrupted if the program was not able to delete the sheet as it was already deleted

Sub Foo ()

    Application.DisplayAlerts = False

    On Error GoTo instructions
    Sheets("NAME OF THE SHEET").Delete

    instructions:

    Sheets.Add After:=Sheets(Sheets.Count)
    ActiveSheet.Name = "NAME OF THE SHEET"

End Sub

Answer 4

As checking for members of a collection is a general problem, here is an abstracted version of Tim's answer:

Function Contains(objCollection As Object, strName as String) As Boolean
    Dim o as Object
    On Error Resume Next
    set o = objCollection(strName)
    Contains = (Err.Number = 0)
    Err.Clear
 End Function

This function can be used with any collection like object (Shapes, Range, Names, Workbooks, etc.).

To check for the existence of a sheet, use If Contains(Sheets, "SheetName") ...

Answer 5

Corrected: Without error-handling:

Function CheckIfSheetExists(SheetName As String) As Boolean
      CheckIfSheetExists = False
      For Each WS In Worksheets
        If SheetName = WS.name Then
          CheckIfSheetExists = True
          Exit Function
        End If
      Next WS
End Function

Answer 6

Without any doubt that the above function can work, I just ended up with the following code which works pretty well:

Sub Sheet_exist ()
On Error Resume Next
If Sheets("" & Range("Sheet_Name") & "") Is Nothing Then
    MsgBox "doesnt exist"
Else
    MsgBox "exist"
End if
End sub

Note: Sheets_Name is where I ask the user to input the name, so this might not be the same for you.
