But my model will be expecting enum data inputs. Whether it will work?

Yes, it should Once the data has been imported, write a script to propagate the enum inputs to your model.

Hi Varunjith,

For the excel sheet to comply with Signal builder while importing, it should not contain non-numeric values. So, try not using non-numeric values in your excel sheet.

Following is the link for a blog, which also covers importing excel sheet into Signal Builder:

I would sugest you to use a 'From Workspace' block or a Root-Level 'Inport' block. Define your singal in the base workspace and pass it to one of those blocks.

This should be a good starting point with links to the possible ways to import your signal:
