This is the LPeg version, though it's stricter about following the
actual CSV spec than the solutions above:
local re = require 're'
local csv_sub_re = re.compile [[
file <- {~ record (%nl record)* (%nl / !.) ~}
record <- field ((',' -> '~') field)*
field <- escaped / nonescaped
nonescaped <- [^,"%nl]*
escaped <- '"' ([^"] / '""' )* '"'
]]
newdata = csv_sub_re:match(data)
