In addition to that you can also export the Denodo Data Catalog. You can do this in the *Query* tab when browsing the view. After providing the query definition simply click on* export.*
You can also export your data to csv when using the VQL Shell. If you use the VQL Shell in the Data Catalog, click on *export * and specify your data format, csv in your case. If you use VQL Shell of the Denodo Design Studio you have to click on the button *execute and download* to do the same.
Hope this helps!
