Add : ever two numbers in a cell

All,

I get a spreadsheet every day with over 100 mac address. Unfortunately the mac address don't have the colon separating the numbers. How do I go about formatting a cell to add the colons?

Martin Liss

You can use this macro. It assumes no headings and that the data is in column A.

Sub MacAddress()
Dim lngLastRow As Long
Dim lngIndex As Long
Dim V As String
lngLastRow = Range("A65536").End(xlUp).Row
' Change 1 to 2 if you have a heading
For lngIndex = 1 To lngLastRow
' 1 in these two lines represents column A
    V = Cells(lngIndex, 1).Value
    Cells(lngIndex, 1).Value = Mid(V, 1, 2) & "-" & Mid(V, 3, 2) & "-" & Mid(V, 5, 2) & Mid(V, 7, 2) & "-" & Mid(V, 9, 2) & "-" & Mid(V, 11, 2)
Next

I assume there may be letters in which case you can't use number formatting, if you have an entry like this in A2

0123456789ab

and you want it to look like this

01:23:45:67:89:ab

You could use this formula in B2

=REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(A2,3,0,":"),6,0,":"),9,0,":"),12,0,":"),15,0,":")

I am using office 2010 if that makes a difference. I am getting a compile error. See below

Sub MacAddress()
Dim lngLastRow As Long
Dim lngIndex As Long
Dim V As String
conts COL = 1 ' = column A
lngLastRow = Range("A65536").End(xlUp).Row

For lngIndex = 1 To lngLastRow
V = Cells(lngIndex, COL).Value
Cells(lngIndex, COL).Value = Mid(V, 1, 2) & "-" & Mid(V, 3, 2) & "-" & Mid(V, 5, 2) & Mid(V, 7, 2) & "-" & Mid(V, 9, 2) & "-" & Mid(V, 11, 2)
Next
End Sub

I updated the code. Change conts to Const

@ Martinls

I got it.. I put my glasses on this time and saw you were missing a ":" so I added it and it works great! Thanks!

Sub MacAddress()
Dim lngLastRow As Long
Dim lngIndex As Long
Dim V As String
Const COL = 1 ' = column A
lngLastRow = Range("A65536").End(xlUp).Row

For lngIndex = 1 To lngLastRow
V = Cells(lngIndex, COL).Value
Cells(lngIndex, COL).Value = Mid(V, 1, 2) & ":" & Mid(V, 3, 2) & ":" & Mid(V, 5, 2) & ":" & Mid(V, 7, 2) & ":" & Mid(V, 9, 2) & ":" & Mid(V, 11, 2)
Next
End Sub

The Format function is another option:
Cells(lngIndex, COL).Value = Format(V, "&&:&&:&&:&&:&&:&&")
