Data being saved in a giant csv

Data started being saved in a big csv file instead of separate csv files for each participant for my Builder Pavlovia experiment. I have no idea what happene since all my previous experiments stored the data in separate files and I’m not sure what changed. How do I change this?

On your experiment page on Pavlovia you can switch between CSV and database.

Tried that - doesn’t seem to do anything.

Did you find it switched to database? It only affects future data, not data already collected.
