csv stands for comma separated values but one must define
where to put the commas, so there is no conversion possible
without defining rules where to put the comma.
Assuming there is a text likeDo the right thing. It will gratify some people and astonish the rest.
You can, for example, decide to split the text intoDo the right thing.
andIt will gratify some people and astonish the rest.
then you would put the comma after the first sentence but you can
also decide to split it in three parts then you might possibly choose
which would mean you have to set the first comma after the first sentence
and the second comma after the word people.
So you see there isn’t a one and only way to do this.
If you can provide as a sample text then we might be able to offer
some possible solutions.
