Csv in different formats, create backup data saving

URL of experiment:

Description of the problem:
HI everyone,
I am fairly new to PsychoPy and here is my problem :

When the datas are saved, a new format is created for each participant,
For example the variable A would be saved in B1 for participant 1 and in C3 for participant 2.
Furthermore, it has been pointed that when participants quit the experiment too quickly, datas can’t be saved.

So I’d like to code the creation of some sort of backup clean csv files so I they are all in the same format and I can analyze them more easily.

Any idea how to do that?
Thank you in advance
