Changing ^t to ; using vba

I'm having an issue with some coding regarding vba.

I start with a .txt file downloaded from SAP. I then have to open up the file in excel to make some changes. When the file is downloaded it is seperated by ; , but when I import this into excel it changes the ; to a tab character ^t.

Once I have made the changes I then save the file as .txt file. But I the have the issue of having to change the ^t back to ;. I'm using replace in word to currently do it, but it could be the case that in vba it's not the right way to do it?

I am trying to do this in word using vba at the moment, but it does not seem to work. My code is below:

Sub OpenOstomed1Word()

Const wdReplaceAll = 2

Dim objWord As Object
Dim objSelection As Object
Dim objDoc As Object

Set objWord = CreateObject("Word.Application")
objWord.Visible = True

Set objDoc = objWord.Documents.Open("I:\PC-HC\03.Operations\01.Departmental Access\05.Team Logistic\New Patient Uploader\Files\Ostomed1.txt")
Set objSelection = objWord.Selection

With objSelection.Find.Text = """"
objSelection.Find.Forward = True
objSelection.Find.MatchWholeWord = True

objSelection.Find.Replacement.Text = ""
objSelection.Find.Execute , , , , , , , , , , wdReplaceAll
End With

With objSelection.Find.Text = "^t"
objSelection.Find.Forward = True
objSelection.Find.MatchWholeWord = True

objSelection.Find.Replacement.Text = ";"
objSelection.Find.Execute , , , , , , , , , , wdReplaceAll
End With
