Online experiment saved data was format misplacement

I want to complete this kind of problems.

I’m trying to make a very simple experiment where the participants have to read a text and then to answer to one question. I want to memorize the reading time.
https://gitlab.pavlovia.org/Lecture/textecoco

I have to say that in PythonPy, all works very fine! All the datas are perfectly saved!

The data saved in Pavlovia are in a wrong format. This is an example:

First when we have comma in the stimulus (in the text), it will make a column separation in the csv format file.

Question: is it possible not to save the stimulus in the csv format file? Or is there a way to specify another separator for the csv file.

Second: In the text to read, we have some new-line characters and this generate the same kind of problems…

Maybe the much simpler thing to do is to have an option which allow not to save the stimulus in the csv file?

Thanks for your help! The software is very very useful and in the next few months, I want to engage my students to use it!
