CSV stringifier for Node.js and the web

The csv-stringify package is a stringifier converting records into a CSV text and implementing the Node.js stream.Transform API. It also provides the easier synchronous and callback-based APIs for conveniency. It is both extremely easy to use and powerful. It was first released in 2010 and is tested against big data sets by a large community.

Usage

Run npm install csv to install the full csv module or run npm install csv-stringify if you are only interested by the CSV stringifier.

The module is built on the Node.js Stream API. Use the callback and sync APIs for simplicity or the stream based API for scalability.

Example

The API is available in multiple flavors. This example illustrates the sync API.

import { stringify } from 'csv-stringify/sync';
import assert from 'assert';

const output = stringify([
  [ '1', '2', '3', '4' ],
  [ 'a', 'b', 'c', 'd' ]
]);

assert.equal(output, '1,2,3,4\na,b,c,d\n');

Development

Tests are executed with mocha. To install it, run npm install followed by npm test. It will install mocha and its dependencies in your project "node_modules" directory and run the test suite. The tests run against the CoffeeScript source files.

To generate the JavaScript files, run npm run build.

The test suite is run online with Travis. See the Travis definition file to view the tested Node.js version.
