Usage

This example shows how the second line is tolerated despite having less fields than in the first line.

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

parse(`
a,b,c
d,e
`.trim(), {
  relax_column_count_less: true
}, (err, records) => {
  assert.deepStrictEqual(records, [
    ['a', 'b', 'c'],
    ['d', 'e']
  ]);
});
