Check sheet name and run the code related to the sheet - excel

Question

I' am looking for a code to check Sheet names initially like A, B, C. If sheet A exist then it should run the code which is goto A1: else it should go to B and check if Sheet B exist, if sheet B exist then it should run code below B1, Same way for sheet C as well.
Ex:
For I = 1 to worksheets.count
If Sheets(i).Name = "A" Then
GoTo A1
Else
GoTo B
End If
Next I

Answer 1

I think it can be solved by using ElseIf or Select Case.
Please try with the following 2 cases.
Dim i As Integer
For i = 1 To Worksheets.Count
Select Case Sheets(i).Name
Case "A"
' Coding for "GoTo A1"
Case "B"
' Coding for "GoTo B1"
Case "C"
' Coding for "GoTo C1"
...
End Select
Next i
Or
Dim i As Integer
For i = 1 To Worksheets.Count
If Sheets(i).Name = "A" Then
' Coding for "GoTo A1"
ElseIf Sheets(i).Name = "B" Then
' Coding for "GoTo B1"
ElseIf Sheets(i).Name = "C" Then
' Coding for "GoTo C1"
Else
...
End If
Next i

If you have a specific macro you want to run on each sheet and you want to trigger all of them to run at once, you can organize it like so:
Sub Main()
Call SheetA_Macro
Call SheetB_Macro
Call SheetC_Macro
End Sub
If you have a lot of sheets you can automate the calling of these macros by naming them all the same thing and placing them into the sheet's code module, which would let you call them in this way:
Sub Main()
Dim Sht As Worksheet
For Each Sht In ThisWorkbook.Worksheets
Call ThisWorkbook.Sheets(Sht.Name).MySheetSpecificMacro
Next Sht
End Sub
If you have an unknown sheet and you want to call only that specific sheets macro, then you will want to do it like above but without the loop.
Call ThisWorkbook.Sheets(MyUnknownSheetObject.Name).MySheetSpecificMacro
Remember that the macros must be placed into the sheet's code module and should all be named the same thing.

Worksheet Related Code
Writes the list of worksheet names to an array.
Loops through the array attempting to find an existing worksheet using the WorksheetExists function.
Continues with the worksheet that exists (if any).
Option Explicit
Sub ApplyToFirstFound()
Const wsNamesList As String = "A,B,C"
Dim wb As Workbook: Set wb = ThisWorkbook ' workbook containing this code
Dim wsNames() As String: wsNames = Split(wsNamesList, ",")
Dim wsName As String
Dim n As Long
For n = 0 To UBound(wsNames)
If WorksheetExists(wb, wsNames(n)) Then
wsName = wsNames(n)
Exit For
End If
Next n
' You could continue with...
If n > UBound(wsNames) Then
MsgBox "No worksheet exists.", vbCritical, "ApplyToFirstFound"
Exit Sub
End If
MsgBox "The first found worksheet is named '" & wsName & "'.", _
vbInformation, "ApplyToFirstFound"
' ... continue...
' ... or with a different code for each worksheet (I've used the same.).
Select Case wsName
Case "A"
MsgBox "Applying to '" & wsName & "'.", _
vbInformation, "ApplyToFirstFound"
Case "B"
MsgBox "Applying to '" & wsName & "'.", _
vbInformation, "ApplyToFirstFound"
Case "C"
MsgBox "Applying to '" & wsName & "'.", _
vbInformation, "ApplyToFirstFound"
Case Else
MsgBox "No worksheet exists.", vbCritical, "ApplyToFirstFound"
End Select
End Sub
Function WorksheetExists( _
ByVal wb As Workbook, _
ByVal WorksheetName As String) _
As Boolean
On Error GoTo ClearError
Dim ws As Worksheet: Set ws = wb.Worksheets(WorksheetName)
WorksheetExists = Not ws Is Nothing
Exit Function
ClearError:
Resume Next
End Function
