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. [image]

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 [image]

If it’s anything like the openXML in C# it’s not had an official release for .NET8 yet.

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 [image] Issues · ksobon/archilab this is archi-lab.net dynamo repo. Contribute to ksobon/archilab development by creating an account on GitHub. (FYI @Konrad_K_Sobon )

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. :slight_smile:

thanks guys for the help. Greatly appreciated. . Issue already posted to github. Open XML Version Conflict opened 11:11AM - 04 Dec 24 UTC (UTC) [JoeyJM] JoeyJM …

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?

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.
