Author claims it is editable in regular editors, but there are no newlines there, so it would be just one huge line; I cannot imagine doing any edits other than simplest typos. And with the delimiters so similar, even copy-pasting lines around would be fraught with error. I suppose you can have editor plugin to wrap lines, but if we are talking about editor plugins, might as well use some other well-known format.<p>I don't see why one would ever use it over CSV or JSON/JSONlines or your favorite binary formats.
