Issue with Data.ImportEcxel and SetParameterByName

MenfisCode.dyn (121.3 KB)

Hello everyone! I created a Dynamo script to automate filling in type parameters for architectural elements in Revit.

The process works as follows: every architectural element modeled in Revit has a code in the “Type Mark” parameter. This code serves as a reference to locate the corresponding information for each element in an Excel spreadsheet.

Based on this match, Dynamo automatically populates the “MenfisCode” type parameter in Revit.

This script used to work correctly. However, following an update to Dynamo/Revit, the “Data.ImportExcel” and “SetParameterByName” nodes stopped working. I tried replacing them with the “Excel Reader” package/node, but the script still isn’t working properly.

I would like to know what changes need to be made to the script so that this process works again in Revit 2027/the updated Dynamo version.

I am sharing the original Dynamo file and an example Excel spreadsheet. Can anyone help me?

Go back to the original node. Then post an image of the graph showing any error/warning, and copy the text therefrom so we can see what it is.
