Processing of variable of 'dataset' type into excel

hi @Marius_Taran
This post should help you.

The write range activity needs datatype “DataTable” and you are providing Dataset of type DataSet to it, hence the error. Use “Export Extraction Results” activity as explained in post above after the “Data Extraction Scope” activity which will convert its result into a datatable. This datatable can be then used as input to Write range activity.
