Excel/How to get the series


Hi Bob,

I have a number 12653. In column A, cell a2 there is '12', cell a3 there is '65', cell a4, '253'. This means that at cell a4 I get my whole number '12653' with the previous numbers considered in common. In a given column with a very large number of such different permutations, how can I directly arrive at the cell where all the digits of my original number get reconciled?

Thanks in advance.

Best to use a UDF (User-Defined Function).
In A4, enter =UniqueDigits(A2:A4)

Get to the VBE (Alt/F11), use Insert/Module, put this in:

Function UniqueDigits(Rg As Range) As Long
Dim ans As New Collection, temp As Long
   On Error Resume Next
   For Each thing In Rg
       For i = 1 To Len(thing)
         ans.Add CStr(Mid(thing, i, 1)), CStr(Mid(thing, i, 1))
   n = 0
   For i = ans.Count To 1 Step -1
       temp = ans.Item(i) * 10 ^ n + temp
       n = n + 1
   UniqueDigits = temp
End Function
