Recipe 06: Type coercion and custom parsing

Current version: 3.1.0

Goal

Normalize data types and apply custom parsing logic.

Example

const { csvToJson, isDate } = require('jtcsv');

const csv = 'id,amount,active,created_at
1,9.99,true,2024-01-01';

const rows = csvToJson(csv, {
  delimiter: ',',
  parseNumbers: true,
  parseBooleans: true,
  transform: (row) => ({
    ...row,
    created_at: isDate(row.created_at) ? new Date(row.created_at) : null
  })
});

console.log(rows);

Notes

• parseNumbers and parseBooleans handle the common cases.
• Use transform to normalize dates or custom enums.
