Hi John,
I accidentally answered in Slack which doesn’t post back to the forum
Have you looked at the examples available on the Web? e.g. robotframework read csv file - Google Search. There are some videos as well.
Strangely, I didn’t notice the CSV library in the resources list on RF web page: Robot Framework, so I don’t know if it is recommended, but there is at least one out there mentioned in the search above, as well as example code to read the files yourself. We use the RF DataDriver to pull testcase parameters out of CSV files, but that is row by row.
