As one of our friends mentioned that there is a simple and straight forward way to download the CSV files in Workspace (except data visualizations): Project --> Downlaod CSV
That being said, at times this download option doesn't work effectively (from my personal experience) if your Data-set is heavy and/or the Segments applied are little complex and data-heavy. In this case I would suggest to rely on the PDF File sent by the scheduler using the patch: Share --> Send File Now.
Hope this helps and Don't forget to like the comment
There are two ways you can download a CSV from workspace. From the Left hand side > Project tab > Download CSV which pulls all the freeform data and visualization data counts (not graphs). And the other way, right click from any data table (from your Visualization data) > Download as CSV. For me both ways worked fine and didn't see any issues. You need to save workspace before you want to download as CSV.
