"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi,

pls try

Sub macro()
For Each c In Range("C2:CZ20000")
    If UCase(c) Like "O######" Or UCase(c) Like "E######" Then
        c = "'-"
    End If
Next
End Sub

Open in new window

EDIT Corrected code

also a better one. use below, put this in DA1 and drag left and down.

since you asked for formula solution, here is the formula.

=IF(AND(LEN(C2)=7,(SEARCH("o",LEFT(C2,1),1))=1),SUBSTITUTE(C2,LEFT(C2,1),"e"),C2)

i misunderstood your question, here is the correct formula put this in DA1 and drag left and down

=IF(AND(LEN(C2)=7,OR(ISNUMBER(SEARCH("o",LEFT(C2,1),1)),ISNUMBER(SEARCH("e",LEFT(C2,1),1)))),SUBSTITUTE(C2,LEFT(C2,1),"-"),C2)

Professor Jim jam. ..the formula partly works it still leaves the numbers numerical value...need to remove that too...

So o123456 equal - not 123456
ProfessorJimJamMicrosoft Excel ExpertCommented:
then use this

=IF(AND(LEN(C2)=7,OR(ISNUMBER(SEARCH("o",LEFT(C2,1),1)),ISNUMBER(SEARCH("e",LEFT(C2,1),1)))),SUBSTITUTE(C2,C2,"-"),C2)
