Exit Sub

.Replace what:=BeforeStr, Replacement:=AfterStr, _
lookat:=xlPart, SearchOrder:=xlByRows

after:=.Cells(1), _

searchdirection:=xlNext, _

If FoundCell Is Nothing Then
'done, get out!
Exit Do
End If
FoundCell.Value _

Loop
End With
End With
End Sub

If you're using xl97, change that Replace() to application.substitute()

If you're new to macros, you may want to read David McRitchie's intro at:

Ps. Try it against a copy of your data--just in case!

I am using Excel to query an Access database. The query is pulling in a memo
field from Access. Excel is displaying the carriage control "chr(13)" as a
box. I can do a find replace using "chr(13)" changing it to a space until I
hit a cell that has to much data in it. I am getting a "formula too long"
error. Is there a way to use VB code to address this issue and replace this
"box"?
