VBA Find and Replace using another workbook

[decadence]

Hi, I am trying to do a find and replace part of a string in the selected cell values in Book1-Sheet1 using Book2-Sheet1. Book 2 contains what to search for in a column 1 and the replacement is in the adjacent column. The Find and Replace Values is a long list of over more than 10,000 Rows
Can someone help with this please.

Code Below of what I have so far....

Public Const DesPath As String = "C:\Users\decadence\Lookup Sheets\Replace Data.xlsx"
Public Const DesName As String = "Replace Data.xlsx"
Dim xVal1 as Range, Rng as Range, xVal2 as Range, Rng2 as Range, Fnd as Range
Dim Findtext As String, Replacetext As String
Dim wb1 As Workbook, ws1 As Worksheet, wb2 As Workbook, ws2 As Worksheet

Sub Test()

    Set wb1 = ActiveWorkbook
    Set ws1 = wb1.ActiveSheet
    Set Rng = MyRng
    Workbooks.Open Filename:=DesPath
    Set wb2 = Workbooks(DesName)
    Set ws2 = wb2.Sheets("Replace")
        If SheetExist("Replace") Then
            ws2.Activate
            Set Rng2 = RngDes
            'ActiveWindow.Visible = False
            For Each xVal1 In Rng
                For Each xVal2 In Rng2
                    Findtext = xVal2.Value
                    Replacetext = xVal2.Offset(, 1).Value
                        If xVal1.Value = Findtext Then xVal1.Value = Replacetext
                    Next xVal2
            Next xVal1
         End If
    'Workbooks(DesName).Close False
End Sub

Function MyRng() As Range
    Set MyRng = Intersect(ActiveWindow.Selection, ActiveSheet.UsedRange)
End Function

Function SheetExist(strSheetName As String) As Boolean
    For k = 1 To Worksheets.Count
        If Worksheets(k).Name = strSheetName Then
            SheetExist = True
            Exit Function
        End If
    Next k
End Function

Function RngDes() As Range
    Set Fnd = ActiveSheet.Columns.Find(What:="Find Values", LookIn:=xlValues, LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext)
        If Not Fnd Is Nothing Then
            Set RngDes = Range(Fnd.Offset(1), Cells(Rows.Count, Fnd.Column).End(xlUp))
        End If
End Function

From This
Book1 Sheet1

App is here

This App is void

Not an App

<tbody>

To This
Book1 Sheet1

Apple is here

This Apple is void

Not an Apple

<tbody>
</tbody>

Using This
Book2 Sheet1

Find Values	Replace Values
App	Apple
Ban	Banana

Hi, I am trying to do a find and replace part of a string in the selected cell values in Book1-Sheet1 using Book2-Sheet1. Book 2 contains what to search for in a column 1 and the replacement is in the adjacent column. The Find and Replace Values is a long list of over more than 10,000 Rows

That's a long list indeed. The speed will be an issue here.
And how many rows of data do you have in Book1-Sheet1?

Have you consider a problem:
for example: App to Apple
finding a word as part of a cell (not as a whole) means that if you already have apple or application etc (in Book1-Sheet1), then it will be replaced too, so you will get applele, applelication.
I don't know the real data, do you think it won't be a situation like that?

Hi Akuini, I have managed to sort this now, thanks for your reply

From This

Findtext = xVal2.Value
Replacetext = xVal2.Offset(, 1).Value
If xVal1.Value = Findtext Then xVal1.Value = Replacetext

To This

MyText = xVal1.Text
Findtext = xVal2.Text
Replacetext = xVal2.Offset(, 1).Text
If InStr(1, MyText, xVal2) Then xVal1 = Replace(MyText, Findtext, Replacetext)

Ok, glad you figured it out.
