Re: How to handle extra double quotes in CSVR4?

Maybe one could use RFC 4180 as the official standard when discussing double quotes in CSV. RFC 4180 clearly says:

2. Definition of the CSV Format:

7. If double-quotes are used to enclose fields, then a double-quote
appearing inside a field must be escaped by preceding it with
another double quote.

Following RFC 4180, line "2",""This is a quoted title"","BBB" is quoted incorrectly. The correct line should look like this:

"2","""This is a quoted title""","BBB"

In the second record the double quote pairs seem to throw the
processor off. Has anyone run into this? Any solution?

That is not an Excel-produced CSV. I hesitate to say it's "nonstandard"
because there isn't any official standard for CSV, but it isn't surprising that it's not processed cleanly by a CSV-handling package.

Because it doesn't adhere to... let's call it the predominant dialect of CSV, you may need to process it yourself.

I would infer it ALWAYS surrounds char values in quotes, but then doesn't have any other escape mechanisms. So you can account for that yourself, building your own little miniparser with maybe %split or %scan or something.
