Adding a comma between single digits in a cell

[lind33]

I am looking for a way to add a comma after every single digit in a cell.
I found some formulas on the web but since the number of digits is not equal in the cells, I can't get the result I need.

For example, in column A:
12345
12
135789
135
etc.

What formula can give me the result I need? can I get some help, please? thanks.
Expected results of the above example:
1,2,3,4,5
1,2
1,3,5,7,8,9
1,3,5

Try:

=MID(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1,0,",0"),1,",1"),2,",2"),3,",3"),4,",4"),5,",5"),6,",6"),7,",7"),8,",8"),9,",9"),2,999)

Thanks, Eric. That was quick, and that's hell of a formula

This macro will place the results in column B.

Sub lind33()
    Dim i As Long, rng As Range, RngList As Object
    LastRow = Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
    Set RngList = CreateObject("Scripting.Dictionary")
    For Each rng In Sheets("Sheet1").Range("A1:A" & LastRow)
        For i = 1 To Len(rng)
            RngList.Add Mid(rng, i, 1), Nothing
        Next i
        rng.Offset(0, 1) = Join(RngList.keys, ", ")
        RngList.RemoveAll
    Next rng
End Sub

Yeah, it is quite a formula, isn't it?!

If you have Excel 365 with the TEXTJOIN function, you can simplify it to:

=TEXTJOIN(",",1,MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1))

confirmed with Control+Shift+Enter. But I didn't want to assume you had that. In any event, glad we could help!

Sub lind33()
    Dim i As Long, rng As Range, RngList As Object
    LastRow = Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
    Set RngList = CreateObject("Scripting.Dictionary")
    For Each rng In Sheets("Sheet1").Range("A1:A" & LastRow)
        For i = 1 To Len(rng)
            RngList.Add Mid(rng, i, 1), Nothing
        Next i
        rng.Offset(0, 1) = Join(RngList.keys, ", ")
        RngList.RemoveAll
    Next rng
End Sub

Your macro can be written using only one loop...

Sub AddCommasBetweenDigits()
  Dim X As Long, LastRow As Long, Cell As Range
  LastRow = Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
  For Each Cell In Sheets("Sheet2").Range("A1:A" & LastRow)
    Cell.Offset(, 1) = Replace(StrConv(Cell.Value, vbUnicode), Chr(0), ",", , Len(Cell.Value) - 1)
  Next
End Sub

HOW TO INSTALL MACROs
------------------------------------
If you are new to macros, they are easy to install and use. To install it, simply press ALT+F11 to go into the VB editor and, once there, click Insert/Module on its menu bar, then copy/paste the above code into the code window that just opened up. That's it.... you are done. To use the macro, go back to the worksheet with your data on it and press ALT+F8, select the macro name (AddCommasBetweenDigits) from the list that appears and click the Run button. The macro will execute and perform the action(s) you asked for. If you will need to do this again in this same workbook, and if you are using XL2007 or above, make sure you save your file as an "Excel Macro-Enabled Workbook (*.xlsm) and answer the "do you want to enable macros" question as "yes" or "OK" (depending on the button label for your version of Excel) the next time you open your workbook.

Try whit UDF (User Definition Function)

Function AddComma(s As Range)
    Dim i As Long, cad As String
    For i = 1 To Len(s)
        cad = cad & Mid(s, i, 1) & ","
    Next
    AddComma = Left(cad, Len(cad) - 1)
End Function

Use like formula excel:

=AddComma(A1)

Actually Eric, this can be done with a "simple" normally-entered formula in any version of Excel (that I am familiar with)...

=MID(TEXT(A1,REPT("\,0",LEN(A1))),2,2*LEN(A1))

Thank you, guys all, for your great answers really. I appreciate it.

Try whit UDF (User Definition Function)

Function AddComma(s As Range)
    Dim i As Long, cad As String
    For i = 1 To Len(s)
        cad = cad & Mid(s, i, 1) & ","
    Next
    AddComma = Left(cad, Len(cad) - 1)
End Function

Use like formula excel:

=AddComma(A1)

Given the formula I posted in Message #8 , a UDF for this functionality (if one was thought to be necessary now) could be written as a non-looping one-liner...

Function AddCommas(s As String) As String
  AddCommas = Evaluate(Replace("MID(TEXT(@,REPT(""\,0"",LEN(@))),2,2*LEN(@))", "@", s))
End Function
