Default behavior

The quote option default to ". Fields do not need to be quoted as illustrated in this example:

import assert from 'node:assert';
import { parse } from 'csv-parse/sync';

const records = parse(`
a,"b",c
"d",e,"f"
`.trim());

assert.deepStrictEqual(
  records, [
    ['a', 'b', 'c'],
    ['d', 'e', 'f']
  ]
);

Quotes inside the field

Quote characters present inside a field must be escaped. The default escape character is ".

This example contains quotes inside the second field:

import assert from 'node:assert';
import { parse } from 'csv-parse/sync';

const records = parse(`
a,"b""b",c
d,"e""e",f
`.trim());

assert.deepStrictEqual(
  records, [
    ['a', 'b"b', 'c'],
    ['d', 'e"e', 'f']
  ]
);
