### Missing numbers (vba)

The macro demonstrated here let´s you select a cell range (values must be in a single column), start and end number.

A new sheet is created, values are sorted in the first column. The second column (B) contains all missing values.

### VBA

Sub Missingvalues() Dim rng As Range Dim rng1 As Range Dim StartV As Double, EndV As Double, i As Double, j As Single Dim k() As Double Dim WS As Worksheet ReDim k(0) On Error Resume Next Set rng = Application.InputBox(Prompt:="Select a range:", _ Title:="Extract missing values", _ Default:=Selection.Address, Type:=8) StartV = InputBox("Start value:") EndV = InputBox("End value:") On Error GoTo 0 Set WS = Sheets.Add WS.Range("A1:A" & rng.Rows.CountLarge).Value = rng.Value With WS.Sort .SortFields.Add Key:=WS.Range("A1"), _ SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal .SetRange Range("A1:A" & rng.Rows.CountLarge) .Header = xlNo .MatchCase = False .Orientation = xlTopToBottom .SortMethod = xlPinYin .Apply End With MsgBox "test" Set rng1 = WS.Range("A1:A" & rng.Rows.CountLarge) For i = StartV To EndV On Error Resume Next j = Application.Match(i, rng1) If Err = 0 Then If rng1(j, 1) <> i Then k(UBound(k)) = i ReDim Preserve k(UBound(k) + 1) End If Else k(UBound(k)) = i ReDim Preserve k(UBound(k) + 1) End If On Error GoTo 0 Application.StatusBar = i Next i WS.Range("B1") = "Missing values" WS.Range("B2:B" & UBound(k) + 1) = Application.Transpose(k) End Sub

How to find missing nos which starts with B0001 or S-001

Dear Osacar Sir,

Please send me solution for finding missing nos starting with J000001 or S000001

Chetan Sonawane,

Create a new column and remove J and S from your lists.

If your list is in column A, cell B1:

=RIGHT(A1,LEN(A1)-1)*1

Copy formula downwards as far as needed.

Start macro and use it on column B.

Dear Sir,

Instead of formula can you help me with VBA code, If you can please modify VBA code for finding missing nos starting with J000001 or S000001
