You can use the QRadar interactive API interface to run your query. When you successfully run a GET against the reference set API, the interface provides a CURL command to run that query from the command-line.
When you've got your command-line CURL example, you just need to add an output to your CURL command to write the json data (just append -o myjsonrefset.json), then you can convert it as needed to CSV.
There are multiple tools to do this from your workstation, like JSON2CSV, csvkit, Python, or even in R where you can format and work with the data.
