Questions

How are commas inside cells handled?

On the way to CSV, cells with commas, quotes or line breaks are quoted. On the way back, quoted cells are unescaped.

Can I convert an arbitrary JSON object?

JSON to CSV expects an array of objects. A single object or an array of numbers is refused so the columns stay honest.
