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)
