Hi all,
Using dynamo 3.2 and I am struggling to get any of my older scripts to successfully export to excel.
I have since turned to the newer Open XML Excel exporter but keep getting this error. Has anyone else seen this error? I feel like it’s something obvious i am missing.
If it’s anything like the openXML in C# it’s not had an official release for .NET8 yet.
Hi,
it’s rather a library conflict coming from a third-party addin that doesn’t use the right version of openXML
@jm_cop_de try to disable addins and re-test, if it fails again try to remove Dynamo packages
Hi Cyril yes you are right! I’ve narrowed it down to the archi-lab package.
Shame to remove this as there’s some great nodes there. Are any of you able to replicate this?
you can report the issue here
(FYI @Konrad_K_Sobon )
A near certainty that you are using the wrong version of Archi-Lab. Read the linked post carefully, and note that you need a version ending with the same last two digits as your Revit version.
Hi Jacob thanks for the reply. That’s good to know but I don’t think that is the problem as it is the latest release of archi-lab - version 2025.300.1225. (I’m running Revit 2025)
Yep - you’re in the right build. Best to surface to the GitHub linked above then. 
thanks guys for the help. Greatly appreciated. .
Issue already posted to github.
I use this Data.OpenXMLExportExcel node to create .xlsx files in the background as opposed to having Excel open. The ExportToExcel nodes works just fine with ArchiLab installed.
Does anyone have a solution how to close the Excel file within Dynamo after it has opened?
