What did you do?

Ran a Script using OOTB node Data.OpenXMLImportExcel to read Excel data.

What did you expect to see?

In R23, this node works; imports excel data with similar functionality to OOTB node ImportExcel (but without using Interop).

What did you see instead?

Node fails with Warning: Data.OpenXMLImportExcel operation failed. Could not load file or assembly:

OpenXMLImportExcel failed in my script in Revit 2025. Made a simple test for the node and still wouldn't work.

do you have any addins installed in 2025 that are not in 2023?
Do you see any reported conflicts in the notifications in Dynamo menu?
can you attach a log from %appData%/Dynamo yada yada /logs

@david-pbk Can you use legacy ImportExcel node as a workaround?
Can you also provide the exact Revit version you have?

FYI @Mikhinja
