Have you thought about using XML. XML is the ideal format.
There are plenty of API’s available to parse the format and it
is more reliable.

For instance, in a CSV file

a, comment, with, commas, is, a, problem

or “ “ is this empty?

Also there is an issue with the disordering of data.

I could probably go on and on, but will spare you.

XML is worth learning, because it solves all these problems and more.
