Unicorns can just add .xml or .json to the end of the URL of a rack.

e.g.
modulargrid.net/e/racks/view/223662
->
modulargrid.net/e/racks/view/223662.xml
modulargrid.net/e/racks/view/223662.json

Not CSV but maybe a useful workaround?

Thanks, both formats are useful. Doesn't work with private racks, but I can workaround that too!
