How can I export a CSV?

You can export a number of reports at the same time as a CSV, from the web app. Simply highlight reports you want, then click Export – CSV – Full Export. You’ll have to sort by media type (for instance, Artwork/Object – Basic, Painting – Basic, Painting – Standard, Painting – Detailed, etc.) if you do a full export – otherwise you’d have hundreds of fields in your spreadsheet.
