Como importar un archivo de texto (txt) a Excel con mas de 32767 lineas

El problema con grandes archivos es que para importarlos solo realizará dicha accion hasta la fila 32767, es decir, si tu archivo de texto es mayor, tendras que importar paso a paso los 32767 filas manualmente.
No obstante para eso existe la siguiente macro que hará este tedioso trabajo por ti.

Sub LargeFileImport()

'Dimension Variables
Dim ResultStr As String
Dim FileName As String
Dim FileNum As Integer
Dim Counter As Double
'Ask User for File's Name
FileName = InputBox("Please enter the Text File's name, e.g. test.txt")
'Check for no entry
If FileName = "" Then End
'Get Next Available File Handle Number
FileNum = FreeFile()
'Open Text File For Input
Open FileName For Input As #FileNum
'Turn Screen Updating Off
Application.ScreenUpdating = False
'Create A New WorkBook With One Worksheet In It
Workbooks.Add template:=xlWorksheet
'Set The Counter to 1
Counter = 1
'Loop Until the End Of File Is Reached
Do While Seek(FileNum) <= LOF(FileNum)
'Display Importing Row Number On Status Bar
Application.StatusBar = "Importing Row " & _
Counter & " of text file " & FileName
'Store One Line Of Text From File To Variable
Line Input #FileNum, ResultStr
'Store Variable Data Into Active Cell
If Left(ResultStr, 1) = "=" Then
ActiveCell.Value = "'" & ResultStr
Else
ActiveCell.Value = ResultStr
End If

'For xl97 and later change 16384 to 65536
If ActiveCell.Row = 65536 Then
'If On The Last Row Then Add A New Sheet
ActiveWorkbook.Sheets.Add
Else
'If Not The Last Row Then Go One Cell Down
ActiveCell.Offset(1, 0).Select
End If
'Increment the Counter By 1
Counter = Counter + 1
'Start Again At Top Of 'Do While' Statement
Loop
'Close The Open Text File
Close
'Remove Message From Status Bar
Application.StatusBar = False

End Sub
