One very quick solution to this without using a microflow is ; add Export to CSV button to the grid and hide the attributes you dont want to downmload (by deleting them from the view or by giving them 0 width on the grid options). CSV supposed to have only the ones you see. I hope this works for you.
you can try the csv module in marketplace to export as csv
check the below medium link of Import and Export Data in Mendix using the CSV Module
