Excel rename sheet with if sheet name already exists - excel

Question

How can i rename a sheet and add a number to the end of the name if the name already exists.
I'm using this code but need to add a number to the end of sheet name if name already exists.
VBA_BlankBidSheet.Copy After:=ActiveSheet
ActiveSheet.Name = "New Name"

Answer 1

The code below loops through all worksheets in ThisWorkbook and checks if there is already a sheet with a name of "New Name", if it does it adds a number at the end.
Sub RenameSheet()
Dim Sht As Worksheet
Dim NewSht As Worksheet
Dim VBA_BlankBidSheet As Worksheet
Dim newShtName As String
' modify to your sheet's name
Set VBA_BlankBidSheet = Sheets("Sheet1")
VBA_BlankBidSheet.Copy After:=ActiveSheet
Set NewSht = ActiveSheet
' you can change it to your needs, or add an InputBox to select the Sheet's name
newShtName = "New Name"
For Each Sht In ThisWorkbook.Sheets
If Sht.Name = "New Name" Then
newShtName = "New Name" & "_" & ThisWorkbook.Sheets.Count
End If
Next Sht
NewSht.Name = newShtName
End Sub

The test procedure on a new workbook will generate these sheet names:
Sheet1_1, Sheet2_1 and ABC.
If Sheet1_1 exists and we ask for a new Sheet1 it will return Sheet1_2, as ABC doesn't exist in a new workbook it will return ABC.
The Test code adds a new sheet called 'DEF'. If you run it a second time it will create 'DEF_1'.
Sub Test()
Debug.Print RenameSheet("Sheet1")
Debug.Print RenameSheet("Sheet2")
Debug.Print RenameSheet("ABC")
Dim wrkSht As Worksheet
Set wrkSht = Worksheets.Add
wrkSht.Name = RenameSheet("DEF")
End Sub
Public Function RenameSheet(SheetName As String, Optional Book As Workbook) As String
Dim lCounter As Long
Dim wrkSht As Worksheet
If Book Is Nothing Then
Set Book = ThisWorkbook
End If
lCounter = 0
On Error Resume Next
Do
'Try and set a reference to the worksheet.
Set wrkSht = Book.Worksheets(SheetName & IIf(lCounter > 0, "_" & lCounter, ""))
If Err.Number <> 0 Then
'If an error occurs then the sheet name doesn't exist and we can use it.
RenameSheet = SheetName & IIf(lCounter > 0, "_" & lCounter, "")
Exit Do
End If
Err.Clear
'If the sheet name does exist increment the counter and try again.
lCounter = lCounter + 1
Loop
On Error GoTo 0
End Function
Edit: Removed the Do While bNotExists as I wasn't checking bNotExists - just using Exit Do instead.

Building on Darren's answer, I thought it might be easier to just rename the sheet right away instead of returning the name that can be used. I also refactored a bit. Here's my take:
Private Sub nameNewSheet(sheetName As String, newSheet As Worksheet)
Dim named As Boolean, counter As Long
On Error Resume Next
'try to name the sheet. If name is already taken, start looping
newSheet.Name = sheetName
If Err Then
If Err.Number = 1004 Then 'name already used
Err.Clear
Else 'unexpected error
GoTo nameNewSheet_Error
End If
Else
Exit Sub
End If
named = False
counter = 1
Do
newSheet.Name = sheetName & counter
If Err Then
If Err.Number = 1004 Then 'name already used
Err.Clear
counter = counter + 1 'increment the number until the sheet can be named
Else 'unexpected error
GoTo nameNewSheet_Error
End If
Else
named = True
End If
Loop While Not named
On Error GoTo 0
Exit Sub
nameNewSheet_Error:
'add errorhandler here
End Sub

The .net version of VB uses the Try ... Catch formulation to catch runtime errors, see {https://msdn.microsoft.com/en-us/library/ms973849.aspx}(https://msdn.microsoft.com/en-us/library/ms973849.aspx) for a comparison with the old "on error" formulation of VB6 and before. It is better suited to do what you want, and will make shorter exception runs imho.
I'm trying to find out what exception is thrown when trying to rename to an existing sheetname, and will edit here to a workable script when i find it.
