Excel VBA

What I am trying to do is write a macro that applies a formatting to the the B colum n from cell 2 down. It will duplicate the value in column a - but add dashes to it - like from 1234567891234 to this 12345-67891-234 in that format too 5/5/3

This is what I have - and I have changed it many times already

appreciate your help

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim i As Integer
Dim istart As Long



Set i = 2 - 1000

Set istart = B2



Do Until Record Is Null

Sheets("ProdAtt").Range.istart = Mid(A, 1, 5) & "-" & Mid(A, 6, 5) & "-" & Mid(A, 11, 3)

Loop



End Sub

Open in new window

I'm restating your question to make sure I understand what you want to happen.

You would like a macro to automatically populate a formatted value in column B whenever a new value in column A is added or changed.  The value in B should be of the following format:
xxxxx-xxxxx-xxx

1) What is "Record"?   There is no built-in name or operation in VBA for this.
2) What happens if the value in A is not exactly 13 characters long?
3) Do you want this to run every time ANY cell is changed on the worksheet?

Here's an example of a way to produce a formatted string like you described:
Option Explicit
Dim boolChange As Boolean
Private Sub Worksheet_Change(ByVal Target As Range)
    If boolChange Then Exit Sub
    Dim rng As Range
    Dim c As Object
    Set rng = Range("a2:a1000")
    
    For Each c In rng
        If c.Value <> "" Then
            boolChange = True
            If Len(c.Value) = 13 Then
                c.Offset(0, 1).Value = Mid(c, 1, 5) & "-" & _
                          Mid(c, 6, 5) & "-" & _
                          Mid(c, 11, 3)
            Else
                c.Offset(0, 1).Value = "Not a Valid Value"
            End If
        Else
            boolChange = False
            Exit Sub
        End If
    Next c

End Sub

Open in new window


If the value in column A does not have 13 characters, a message will display in column B.  This only affects rows 2:1000; that can easily be optimized, but I wanted you to see a structure that was similar to your initial attempt.

So you want the 13 digit value in column replicated in column B but with the dashes inserted.

Why not just the MID function like you have done in the code but in a formula in column B? As column A expands a simple double click of the bottom right hand corner of the last formula in column B will populate the rest of the cells in column B.

Alternatively, you can use Custom format, either in column A or in column B. If in column B the formula in B would simply be =A2 and then custom format would be:

00000"-"00000"-"000

The dashes would only appear in the formatting not in the cell contents.

I agree with Rob that - if you didn't absolutely need the new, 15-character string with the hyphens as a value - either using a concatenated function or a custom format would work:

in cell B2, copied down:
=IF(LEN(A2)=13,LEFT(A2,5)&"-"&MID(A2,6,5)&"-"&RIGHT(A2,3),"Not a valid value")

or
apply this custom format:
#####-#####-###

Only problem with the custom format is that it formats right-to-left, so if the value in column A has anything other than 13 characters, you'll get an undesirable result. Also, the underlying value will still be a number and not a string.
