My true and tried way of dealing with such files was to import them into LibreOffice's Calc and then export them as tab delimited with quotation marks around every string. This worked every time. Sometimes, though, perhaps because of some imperfection in my import routine, it would require an extra character column on the right.

Not easy, but at least I got the process automated and it happily ate whichever files I threw it over about seven years, from dozens of different sources.
