A VBA code to Insert new row if sequential numbering not matching

[MagnusE]

Hello

I'm trying to figure out a code that could insert a new row where the sequential numbering mismatching.

As you can see in the picture a row is missing for POS 2. I would like a code that could insert, in multiple places, during the sequence. For example, in some cases the sheet could be missing POS 3, 8, 15. And even the first POS1 (B2) could also be missing.
The amount of rows could be between 10 to 200

I have no example because I'm a newbie in this area.

Hi MagnusE,

As per description, assumption is that POS will start from 1 and will be in a sequence.

Is the understanding correct ?

Thanks,

Hi & welcome to MrExcel.
How about

Sub MagnusE()
   Dim i As Long
   
   For i = Range("B" & Rows.count).End(xlUp).Row To 2 Step -1
      If Cells(i, 2) <> Cells(i - 1, 2) + 1 Then
         Rows(i).Resize(Cells(i, 2) - Cells(i - 1, 2) - 1).Insert
      End If
   Next i
End Sub

Hello Fluff

I get a new row but I also get "Run Time error" 13

Are the values in col B actual numbers, or text?

 

[Fluff]

Do you want the news rows to have the POS# in col B?

Hi MagnusE,

Please use below code:

Sub InsertmissingRows()
    Dim rowNo As Integer, pos As Integer, noOfRowsReqd As Integer
    pos = 1
    rowNo = 2   
    Application.ScreenUpdating = False
   
    With ActiveSheet
        Do While .Range("B" & Rows.Count).End(xlUp).Row >= rowNo
            If .Range("B" & rowNo) >= rowNo Then
                    noOfRowsReqd = .Range("B" & rowNo) - rowNo - 1
                    .Range(rowNo & ":" & rowNo).EntireRow.Insert
            End If
            rowNo = rowNo + 1
        Loop
    End With
   
   Application.ScreenUpdating = True
End Sub
