Modified from a previous post:

Option Explicit
Sub testme01()

Dim FoundCell As Range
Dim ConstCells As Range
Dim BeforeStr As String
Dim AfterStr As String

BeforeStr = ",,"
AfterStr = ","

With ActiveSheet
Set ConstCells = Nothing
On Error Resume Next
Set ConstCells = .Cells.SpecialCells(xlCellTypeConstants, _
xlTextValues)
On Error GoTo 0

If ConstCells Is Nothing Then
MsgBox "Select some cells in the used range"
Exit Sub
End If

With ConstCells
'get as many as we can in one step
.Replace what:=BeforeStr, Replacement:=AfterStr, _
lookat:=xlPart, SearchOrder:=xlByRows

Do
Set FoundCell = .Cells.Find(what:=BeforeStr, _
after:=.Cells(1), _
LookIn:=xlValues, _
lookat:=xlPart, _
SearchOrder:=xlByRows, _
searchdirection:=xlNext, _
MatchCase:=False)

If FoundCell Is Nothing Then
'done, get out!
Exit Do
End If
FoundCell.Value _
= Replace(FoundCell.Value, BeforeStr, AfterStr)
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!

Hi,

Using Excel 2000

Example

In a cell I have the following: R541,R542,R543,R587,R588,,R689,R780,
.............................

After R588 there are 2 commas where there should only be 1, this is how
the data is extracted from our quotes system and nothing can be done
about it

Trying to replace the 2 commas with only 1 comma returns a formula too
long error when there is a large amount of data in the cell (4542
characters is when the error first appeared)

Anybody know of any function which will do the required task without
receiving the error

Thanks in advance

Raymond Allan
