Hello, kk.operator

To solve your problem, please apply the following code:

Sub EmailHylink()
'updateby Extendoffice
    Dim xRg As Range
    Dim yRg As Range
    Dim xCell As Range
    Dim xCell2 As Range
    Dim xAddress As String
    Dim xUpdate As Boolean
    Dim xRegEx As Object
    Dim arrSplit() As String
    
    On Error Resume Next
    xAddress = Application.ActiveWindow.RangeSelection.Address
    Set xRg = Application.InputBox("Please select the data range", "Kutools for Excel", xAddress, , , , , 8)
    Set yRg = Application.InputBox("Please select the save range", "Kutools for Excel", xAddress, , , , , 8)
    If xRg Is Nothing Then Exit Sub
    If yRg Is Nothing Then Exit Sub
    Set yRg = yRg.Range("A1").Resize(xRg.Rows.Count, xRg.Columns.Count)

    xUpdate = Application.ScreenUpdating
    Application.ScreenUpdating = False
    
    Set xRegEx = CreateObject("VBSCRIPT.REGEXP")
    With xRegEx
        .Pattern = "^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$"
        .Global = True
        .IgnoreCase = True
    End With
    
    For I = 1 To xRg.Rows.Count
        For J = 1 To xRg.Columns.Count
            Set xCell = xRg.Cells(I, J)
            Set xCell2 = yRg.Cells(I, J)
            If xRegEx.test(xCell.Value) Then
                arrSplit = Split(xCell.Value, "@")
                 If UBound(arrSplit, 1) = 1 Then
                    xCell2.Value = "http://www." & arrSplit(1)
                    xCell2.Hyperlinks.Add Anchor:=xCell2, Address:=xCell2.Value
                 End If
            End If
        Next
    Next
    Application.ScreenUpdating = xUpdate
End Sub

Please have a try, hope it can help you!

The equivalent for the ALT key is the command key (located to the left of the Option Key).

Both of these keys are located to the left of the spacebar.
