If this is in JavaScript then create a literal csv variable. You do not need to bother with the field names in it, at least I don't worry about them. This would be a csv line that you could import. Just make sure the fields are in the same order as your clist.
55,"Bluto","08/09/2019"
You would just make that your csv variable in your code and do the importFromCSV. How are you trying to do this? JavaScript? Python? Post that and I can try and help some more. I always find it easier to use an SDK but it is possible to do it without fairly easily too.
If you do not want to use an SDK or cannot and must use xml and do it the way QuickBase says then if you look at the documentation for API_importFromCSV it says this under the records_csv part, which should be more easily understood than the one you posted. I'm not sure what happened but it seems like you are looking at the html code of the page instead?
