I followed the sample file “OpenXMLImport_Data From Excel.dyn”, and now I am getting a different set of errors. It seems the graph is running further than before, but it still does not complete successfully. I may still be missing something in the configuration. I have attached the updated Dynamo f…

Pin open the data preview from the excel node and the list transpose node.
