The article talks about reading and parsing CSV data of unknown variants, but then skips to the solution being using a different format altogether. But you can only switch to a different format if you are producing data, not if you are reading it!

And if you are in control of producing data, just produce strict RFC 4180-compliant CSV data and everybody will be able to read it just fine. There is no need to make your reader’s lives difficult by using yet another non-standard data format.
