Actually the Error Checking feature can detect 8 faux pas' as Excel sees it.
The one you mentioned isn't really 'unique formula' but rather 'inconsistent
formula' which is not exactly the same thing.

Anyway to detect the errors a cell may have you can use code like this.
This code reports errors regardless of whether error checking is enabled or
what rules are selected. Also it reports all errors that apply, not just
the first.

Sub TestActiveCell()
Dim ErrDesc As String
ErrDesc = GetErrType(ActiveCell)
If ErrDesc < "" Then MsgBox GetErrType(ActiveCell)
End Sub

Function GetErrType(Rg As Range) As String
Dim Counter As Integer
Dim ErrObj As Error
Dim ErrText As String
For Counter = 1 To 8
Set ErrObj = Rg.Errors(Counter)
If ErrObj.Value Then
ErrText = ErrText & Choose(Counter, "Formula is Error", _
"2 Digit Year", "Number as Text", "Inconsistent Formula", _
"Omitted Cells", "Unlocked Formula", "Empty Ref Cell", _
"Data Validation Error") & ","
End If
Next
If ErrText < "" Then _
GetErrType = Left(ErrText, Len(ErrText) - 1)
End Function
