Create a low/high range of postal codes

[kijake]

Hi,

I have a list of postal codes arranged on 1 column of around 13000 rows.
Some of these postal codes could be collapsed and setup in ranges since they are consecutive like in the example below:

121012 and 121013 could be collapsed in 1 row as Low:121012 High:121013

Anyone with a solution to this?

Hi & welcome to MrExcel.
How about

Sub kijake()
   Dim Ary As Variant, Nary As Variant
   Dim r As Long, nr As Long
   
   Ary = Range("C2", Range("C" & Rows.count).End(xlUp)).Value2
   ReDim Nary(1 To UBound(Ary), 1 To 2)
   Nary(1, 1) = Ary(1, 1)
   For r = 1 To UBound(Ary) - 1
      If Ary(r, 1) <> Ary(r + 1, 1) - 1 Then
         nr = nr + 1
         Nary(nr, 2) = Ary(r, 1)
         Nary(nr + 1, 1) = Ary(r + 1, 1)
      End If
   Next r
   Nary(nr + 1, 2) = Ary(r, 1)
   Range("F2").Resize(nr + 1, 2).Value = Nary
End Sub

Thanks a lot, it worked!
In the meantime, I managed to find a much more manual solution.
- by calculating the difference between each postal code
- each occurrence where the difference is = 1 is define as the Low start of a range
- I then created a pivot table by setting my Low postal codes as rows, and my High postal codes as the data with field setting MAX

The result was the exact same as yours by much more time consuming. I'm not a VBA guy at all, so thanks again!
