Hello,

I’m trying to combine @Kulkul, @Chandrasekar_Rajaman and @alejandro.daras work in this topics

> Hi All, I have checked the earlier discussions on this subject but I guess my requirement is slightly different. FYI, I am using Dynamo 1.2 and Revit 2016. Intent steps: Read Excel file for a number of values including Parameter Type, Parameter Group and Category Split Excel column-wise as lists (I will manage the Excel to match the length of lists to be the same). In the future, I intend to even create a drop-down for lesser possibility of error. Use this data to create Shared Parameters …

> Do you know if it is possible to add several Shared Parameters to several categories (e.g. Walls and Floors) at the same time using this node? I do not know how to combine several categories into a list in order to feed the node. It gives me “NULL”. [image] @Kulkul I am not sure if you have solved it before. Thank you in advance.

In fact, I’m trying to generate Shared Parameters in a Revit file, and create project parameters on multiple categories same that this old [post](https://forum.dynamobim.com/t/create-shared-parameter-by-excel-multicategory/33517) .

I tried the following solution duplicating the parameters in a second column but the script does’nt understand the second One as the parameters already exists.

Is there a syntax that could help to do this ? This is quite efficient as we can create an Excel file from a Mindmap with all parameters informations.

Example from an Xmind file :

Eventually, If there is a method to also access to the tooltip from the same File it would be great (as asked [here](https://forum.dynamobim.com/t/shared-parameters-with-data-managed-from-excel-list/7002/28) )
