in word winword vba it refers to word Range explicitly. As you have moved the code to excel it is taking that as excel range.
Dim WdApp As Word.Application, wdDoc As Word.Document
Set WdApp = Word.Application
Dim Tbl As Table
With WdApp.ActiveDocument
For Each Tbl In .Tables
If Tbl.Cell(1, 2).Range.Text = Chr(13) & Chr(7) Then
Tbl.Select
Selection.MoveLeft Unit:=wdCharacter, Count:=3
Dim myRange As Word.Range
Set myRange = Selection.Range
myRange.End = WdApp.ActiveDocument.Range.End
myRange.Delete
Exit Sub
End If
Next Tbl
End With
