If not, I would have expected the script to error out (missing a required arg?) but perhaps it's carrying on with null/empty value and that's why you're getting a csv with no name?</P> Sat, 21 Dec 2019 12:06:22 GMT https://community.splunk.com/t5/Splunk-Dev/Custom-Python-Command-to-read-a-CSV-file/m-p/471412#M8461 martynoconnor 2019-12-21T12:06:22Z
