CSV for Node.js and the web

The csv project provides CSV generation, parsing, transformation and serialization for Node.js.

It has been tested and used by a large community over the years and should be considered reliable. It provides every option you would expect from an advanced CSV parser and stringifier.

This package exposes 4 packages:

csv-generate (GitHub), a flexible generator of CSV string and Javascript objects.
csv-parse (GitHub), a parser converting CSV text into arrays or objects.
csv-stringify (GitHub), a stringifier converting records into a CSV text.
stream-transform (GitHub), a transformation framework.

Documentation

The full documentation for the current version is available here.

Usage

Installation command is npm install csv.

Each package is fully compatible with the stream 2 and 3 specifications. Also, a simple callback-based API is always provided for convenience.

Sample

This example uses the Stream API to create a processing pipeline.

// Import the package
import * as csv from '../lib/index.js';

// Run the pipeline
csv
// Generate 20 records
  .generate({
    delimiter: '|',
    length: 20
  })
// Transform CSV data into records
  .pipe(csv.parse({
    delimiter: '|'
  }))
// Transform each value into uppercase
  .pipe(csv.transform((record) => {
    return record.map((value) => {
      return value.toUpperCase();
    });
  }))
// Convert objects into a stream
  .pipe(csv.stringify({
    quoted: true
  }))
// Print the CSV stream to stdout
  .pipe(process.stdout);

Development

This parent project doesn't have tests itself but instead delegates the tests to its child projects.
