I need to use a function or procedure to find the last o in each cell
in column(a)
Can anyone please help thanks.

I'm interpreting your request as wanting to find the position of the
last 0 in the cell.

Assuming your data starts in A1 and you want the zero positions in B1

The following is one procedure.

Sub FindLastZero()
Dim MyString As String
Dim iZeroPos As Integer, icount As Integer
Dim rStart As Range

Set rStart = Range("a12")
Do While rStart.Offset(icount, 0) <> ""
MyString = StrReverse(rStart.Offset(icount, 0))
If InStr(1, MyString, "0") <> 0 Then
iZeroPos = WorksheetFunction.Find("0", MyString)
iZeroPos = Len(MyString) - iZeroPos + 1
rStart.Offset(icount, 1) = iZeroPos
End If
icount = icount + 1
Loop
End Sub

Ooops, sorry. That first line after the Dim Statements should have
been

Set rStart = Range("a1")

Define the name seq referring to =ROW(INDIRECT("1:1024")). Then use
formulas like

=LOOKUP(2,1/(MID(A1,seq,1)="0"),seq)

Or skip the defined name and use

=LOOKUP(2,1/(MID(A1,ROW(INDIRECT("1:1024")),1)="0"),ROW(INDIRECT("1:1024")))
 
In your example, all the 0's are leading zeroes. Is this true in general?
In other words, can we rule out something like 01290a as a possible value?
If all zeroes will be leading 0's, then the most straightforward formula (at
least to my way of thinking) is

=LEN(A1)-LEN(SUBSTITUTE(A1,"0",""))

If all zeroes are not necessarily leading 0's, and you want the position of
the last leading zero, then this array formula (entered with
CTRL-SHIFT-ENTER) will work:

=MIN(IF(MID(A1,ROW($1:$1024),1)<>"0",ROW($1:$1024)))-1

If all zeroes are not necessarily leading, and you really want the position
of the last zero, you can use some of the other responses.
