Hmmm looks fine for a non-password protected excel.
The workbook activities activity also won’t need any configuration/installation of excel as compared to the excel scope activities.
Why don’t you try the workbook write-range activity again with a different excel, just do something simple like write a datatable with 1 row in it?
That will help you isolate whether is there an issue with the uipath activity, or perhaps some issues with the previous excel file instance.
