Ugh...horrible application. I haven't banged against the edge
cases on this, but for fairly "clean" source data, you might try
the following:
:%s/\%(^\|,\)"\zs.\{-}\ze"\%($\|,\)/\=substitute(submatch(0),'"',
'""','g')/g
It may fail on pathological cases where you have a string like
...,"She said "hello", to me",...
because of the comma-after-the-quote (the regexp doesn't check
for internal quote-parity) but otherwise, it should knock out the
worst offenders so you can focus on the pathological that may remain.
