Perfect! This worked for me after searching for many days on this issue. Thanks.
Tried this again today on my work computer, after a reboot, and still no joy. Rebuilt…
Just noticed I never came back with what worked for me. Repairing Office did not fix the Dynamo issue, or the macros issue, for me. We finally did a clean uninstall of Office and then reinstalled it. Both the Dynamo read node and macros in Excel worked after that.
