Hi,
I was hoping that I could add domains through the feature layer in ArcGIS online (Data, fields, edit List of Values (Domains)).
My goal is to be able to download a excel file which would have the correct names for our database directly from the feature layer in ArcGIS online or from (data, export) in Survey123 web.

From here I would just need to add domains such as scientific names for our database and get rid of the symbol underscore ( _ ) that appears in the excel table when downloaded.

I thought that this could be done from the feature layer in ArcGIS online but they still don't display correctly.

Would anyone know how I could get rid of this underscore (_) in the species name or how to add domains that stick?
Thank you
Jeremy
