I have a saas for non-devs to open big CSVs, so code I've written has parsed thousands of garbage CSVs (and failed to parse thousands others).

Lots of pitfalls are easy to avoid if you already know them, which it sounds like you do. The author is saying that most engineers aren't aware of these issues, and the author is correct.

Writing a for loop is easy, but so is using a language's built in CSV writer.
