Splitting a cell column value before comparison - excel

Question

I have two spreadsheets, vda.xlsx and main.xlsm. At the moment I'm comparing the values in:
main.xlsm column J
with
vda.xlsx column A
To see if there is a match. If a match is found then the value in column gets highlighted in red.
However the format of the data in vda.xlsx column A has changed .
It used to look like this
1234
Now it looks like this
Test\1234 or Best\1234 or Jest\1234 - it could be anything...
Sp I need to split Test\1234 by the "\" and extract 1234 for comparison.
Any idea how I can accomplish this. This is my code so far:
Sub VDA_Update()
Dim wshT As Worksheet
Dim wbk As Workbook
Dim wshS As Worksheet
Dim r As Long
Dim m As Long
Dim cel As Range
Application.ScreenUpdating = False
Set wshT = ThisWorkbook.Worksheets("Master")
On Error Resume Next
' Check whether vda.xlsx is already open
Set wbk = Workbooks("vda.xlsx")
On Error GoTo 0
If wbk Is Nothing Then
' If not, open it
Set wbk = Workbooks.Open("C:\Working\vda_test.xlsx")
End If
' Set worksheet on vda.xlsx
Set wshS = wbk.Worksheets("imac01")
m = wshT.Cells(wshT.Rows.Count, 1).End(xlUp).Row
' Loop though cells in column J on main.xlsm
For r = 1 To m
' Can we find the value in column C of vda.xlsx?
Set cel = wshS.Columns(1).Find(What:=wshT.Cells(r, 10).Value, _
LookAt:=xlWhole, MatchCase:=False)
If Not cel Is Nothing Then
' If we find a match, then change the text to red
wshT.Cells(r, 10).Font.ColorIndex = 3
End If
Next r
Application.ScreenUpdating = True
End Sub

Use Split(CellValue, "\") to get an array and then retrieve the last item in the array.
Change:
' Loop though cells in column J on main.xlsm
For r = 1 To m
' Can we find the value in column C of vda.xlsx?
Set cel = wshS.Columns(1).Find(What:=wshT.Cells(r, 10).Value, _
LookAt:=xlWhole, MatchCase:=False)
If Not cel Is Nothing Then
' If we find a match, then change the text to red
wshT.Cells(r, 10).Font.ColorIndex = 3
End If
Next r
To something like:
' Loop though cells in column A on vda.xlsx
For r = 1 To m
' Can we find the value in column J of main.xlsm?
cellSplit = Split(wshS.Cells(r, 1).Value, "\")
Set cel = wshT.Columns(10).Find(cellSplit(UBound(cellSplit)), _
LookAt:=xlWhole, MatchCase:=False)
If Not cel Is Nothing Then
' If we find a match, then change the text to red
cel.Cells(1, 1).Font.ColorIndex = 3
End If
Next r
