Saving text data out of the engine

I’m working on a project where I need to get text data (ideally in csv) out of the engine. There are a couple of plugins that do this but I’m using 5.1 (it’s way more stable with some ray tracing stuff) and have a tight deadline so the plugins are unlikely to be updated in time.

Is this something anyone has come up against? I feel I may be missing something obvious but I’m not sure where to look.
