Is there a reason the option to connect to an xlsx database was removed from ORD Version 10.09 or was this an oversight?
Support of Excel in gINT Civil Tools was removed starting in their Update 7 release. The component used for this functionality was deprecated technology and no longer passed security audits. Other discussions I've seen on this reference using gINT Logs as a replacement, but you might want to ask for suggestions on the gINT forum as well.
