Build Status

This 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.


Main features

  • Follow the Node.js streaming API
  • Simplicity with the optional callback API
  • Support for custom formatters, delimiters, quotes, escape characters and header
  • Support big datasets
  • Complete test coverage and samples for inspiration
  • Only 1 external dependency
  • to be used conjointly with csv-generate, csv-parse and stream-transform
  • MIT License


The module is built on the Node.js Stream API. For the sake of simplicity, a simple callback API is also provided. To give you a quick look, here's an example of the callback API:

var stringify = require('csv-stringify');

input = [ [ '1', '2', '3', '4' ], [ 'a', 'b', 'c', 'd' ] ];
stringify(input, function(err, output){


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.
