How to clone an existing View and change the format from table to CSV?
Here are the steps to get you going (referring to the screenprint you added):


Click the drop-down list in the upper-right that says view Working Papers Other, where you should then see another list item with label clone Working Papers Other.
Select (click) on that list item with label clone Working Papers Other.
Note that you'll then have an extra (and same named!) button to the right (or below) the 8 buttons you already have, with the very same label Working Papers Other, and the newly added one will be highlighted (grey / black), and selected.
To improve readability, hurry to go change the line (upper-left) that says "Display name: Working Papers Other" (by clicking on that Working Papers Other link). I suggest you change the Display name to (eg) Working Papers Other (CSV).
Change the line (upper-left) that says "Format: Table | Settings" (by clicking on that Table link). At this point you should be able to change the style of the view from Table to the Views display offered by the Views data export module, with label "Data export".
Tune (refine) the "Settings" of the Data export views display to fit your needs, whereas you can see how the result will look like in the preview near the bottom of your page.
Change the line (upper-middle) that says "Path: /publications/working-pa..." (by clicking on thatPathlink). I suggest you change the path by only adding some suffix such as-csv`.
Don't forget to use the Save button (upper-left) to permanently store the updated configuration of your view.
Click the button (upper-right) that says view Working Papers Other (CSV) (if you used my suggestiuon in item "4.") to actually view (browse) the Views result produced by the various changes described above ... Is it a CSV file that fits your requirements? If not: must be that you did something wrong in the steps described above ...
