processing csv files with line breaks in fields - node.js

Im trying to process a csv file with line breaks (\n) inside the fields. Each field is enclosed in double quotes. Is there any node.js package that can handle this type of csv?

I tried parsing it with readline in node. It detects the lines as seperate records even though they are in the same field.

csv can handle rows containing line breaks:

'use strict'

let csv = require('csv');

let str = `id;name;desc
"1";"name1";"desc
on multiple
line"
"2";"name2";"desc2"`;

csv.parse(str,
    {
        delimiter: ';', // default is ,
        columns: true,  // if the first of the csv line is headers
    },
    (err, data) => {
        if (err) console.log(err);
        console.log(JSON.stringify(data, null, 3));
    });

/* output:
[
   {
      "id": "1",
      "name": "name1",
      "desc": "desc\non multiple\nline"
   },
   {
      "id": "2",
      "name": "name2",
      "desc": "desc2"
   }
]
*/

/* without column: true
[
   [
      "id",
      "name",
      "desc"
   ],
   [
      "1",
      "name1",
      "desc\non multiple\nline"
   ],
   [
      "2",
      "name2",
      "desc2"
   ]
]
*/
