Take a look at the Win32::OLE documentation which can tell you if Excel (OLE automation server) or the object is already open:

Win32::OLE->GetActiveObject(CLASS, DESTRUCTOR) The GetActiveObject() class method returns an OLE reference to a running instance of the specified OLE automation server. It returns undef if the server is not currently active. It will croak if the class is not even registered. The optional DESTRUCTOR method takes either a method name or a code reference. It is executed when the last reference to this object goes away. It is generally considered impolite to stop applications that you did not start yourself.

Win32::OLE->GetObject(MONIKER, DESTRUCTOR) The GetObject() class method returns an OLE reference to the specified object. The object is specified by a pathname optionally followed by additional item subcomponent separated by exclamation marks '!'. The optional DESTRUCTOR argument has the same semantics as the DESTRUCTOR in new() or GetActiveObject().
