VBA Macro Vlookup and Index Match function for dynamic number of sheet

Question

I use a macro to run index match and vlookup functions by recording them manually. The problem is that the sheet target is not always available, sometimes only 3 or 5 sheets only so its totally random

here's the code that I use

Sub Function()

Application.AskToUpdateLinks = False
Application.DisplayAlerts = False
Application.ScreenUpdating = False

is there any way to make the formula run only available sheets on the workbook? because if I run it as is, it always asks to update the formula for the sheet that isn't available on the workbook.

Answer 1

You have to iterate over the sheets in your workbook.

Sub insertCOAandStatusFormulas()

'Pattern of each formula part - $1 as placeholder for sheetname

Dim strPartCOA As String, strPartStatus As String
strPartCOA = "IFERROR(INDEX('$1'!R6C:R2000C,MATCH(RC3,'$1'!R6C3:R2000C3,0)),IFERROR(INDEX('$1'!R6C:R2000C,MATCH(RC3,'$1'!R6C5:R2000C5,0)), "
strPartStatus = "IFERROR(VLOOKUP(RC3,'$1'!R6C3:R2000C12,4,0),IFERROR(VLOOKUP(RC3,'$1'!R6C5:R2000C12,2,0), "


Dim wsTarget As Worksheet
Set wsTarget = ThisWorkbook.Worksheets("Tabelle1")    '--> adjust this to your needs


'build sheet-specific part per formula
Dim strFormulaCOA As String, strFormulaStatus As String
Dim cntSheets As Long, i As Long

Dim ws As Worksheet
For Each ws In ThisWorkbook.Worksheets
    If ws.Name <> wsTarget.Name Then
        strFormulaCOA = strFormulaCOA & Replace(strPartCOA, "$1", ws.Name) & vbCrLf
        strFormulaStatus = strFormulaStatus & Replace(strPartStatus, "$1", ws.Name) & vbCrLf
        cntSheets = cntSheets + 1
    End If
Next

'add equal-sign, remove last comma and add closing brackets
If LenB(strFormulaCOA) > 0 Then

    'XXXX this part is not working XXXX - you would have to find out, how many brackets you have to add and at which position they have to go
    strFormulaCOA = "=" & Left(strFormulaCOA, Len(strFormulaCOA) - 4) & ", ""no value found""" & String((cntSheets * 2), ")")
    strFormulaStatus = "=" & Left(strFormulaStatus, Len(strFormulaStatus) - 4) & ", ""no value found""" & String((cntSheets + 2) + 1, ")")
    
    With wsTarget
        .Range("A6").FormulaR1C1 = strFormulaCOA
        .Range("D6").FormulaR1C1 = strFormulaStatus
    End With
End If

End Sub

You have to make adjustments regarding the brackets - see comment in code
