Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It's not possible without attempting to open the workbook. But you can try opening the file using a dummy password and it will return an error if the password is wrong. If it's not password protected, it will open as normal despite providing a password.

Function IsPasswordProtected(sFile As String) As Boolean

    On Error Resume Next
    Workbooks.Open(Filename:=sFile, Password:="dummypassword").Close SaveChanges:=False
    If Err.Number Then
        IsPasswordProtected = True
    End If
End Function

Sub test()

    MsgBox IsPasswordProtected("C:\tests\Book1.xlsx")
End Sub
