Need help with outputting data to CSV


I am currently working with a professor at my university. I am making an application for him to conduct research studies. As such, I need our program to output a CSV file based on the information I require. I’ve been looking into data tables, but from what I’ve found they seem like they are read-only. How can I output to a CSV file, as well as append data instead of overwriting it? I’d also like to note that I am relatively new to Unreal!

Any help would be greatly appreciated!!
