script to convert all characters in excel sheet to A.

Hi Experts,
Looking for a script that will perform the following
open a given spreadsheet, loop thru all columns/rows and replace all data as follows. (except for first row)
for every character found, replace it with letter A
for every digit found, replace it with 1
should leave any special character like slashes or space intact.

Here is a simple script that would work.. Give it a spin and let me know.

Sub ReplaceAll()
      Dim LastRow As Long
      With ActiveSheet
            LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
      End With

      Dim LastCol As Integer
      With ActiveSheet
            LastCol = .Cells(1, .Columns.Count).End(xlToLeft).Column
      End With
      For j = 1 To LastCol
            For i = 2 To LastRow
                  replStr = Cells(i, j)
                  For n = 1 To Len(replStr)
                        replLtr = Mid(replStr, n, 1)
                        If Asc(replLtr) >= 65 And Asc(replLtr) <= 90 Then
                              Mid(replStr, n, 1) = "A"
                        End If
                        If Asc(replLtr) >= 97 And Asc(replLtr) <= 122 Then
                              Mid(replStr, n, 1) = "A"
                        End If
                        If Asc(replLtr) >= 48 And Asc(replLtr) <= 57 Then
                              Mid(replStr, n, 1) = "1"
                        End If
                  Cells(i, j) = replStr
End Sub
