This project provides CSV parsing and has been tested and used on large input files. It provide every option you could expect from an advanced CSV parser and stringifier.

Documentation for the CSV parser is available here.

Usage

Installation command is npm install csv.

Quick example

// node samples/string.js
var csv = require('csv');
csv()
.from( '"1","2","3","4"\n"a","b","c","d"' )
.to( console.log )
// Output:
// 1,2,3,4
// a,b,c,d

Advanced example

// node samples/sample.js
var csv = require('csv');
csv()
.from.stream(fs.createReadStream(__dirname+'/sample.in'))
.to.path(__dirname+'/sample.out')
.transform( function(row){
  row.unshift(row.pop());
  return row;
})
.on('record', function(row,index){
  console.log('#'+index+' '+JSON.stringify(row));
})
.on('end', function(count){
  console.log('Number of lines: '+count);
})
.on('error', function(error){
  console.log(error.message);
});
// Output:
// #0 ["2000-01-01","20322051544","1979.0","8.8017226E7","ABC","45"]
// #1 ["2050-11-27","28392898392","1974.0","8.8392926E7","DEF","23"]
// Number of lines: 2

Migration

This readme cover the current version 0.2.x of the node csv parser. The documentation for the current version 0.1.0 is available here.

The functions 'from' and 'to' are now rewritten as 'from.' and 'to.'. The 'data' event is now the 'record' event. The 'data' now receives a stringified version of the 'record' event.

Development

Tests are executed with mocha. To install it, simple run npm install, it will install mocha and its dependencies in your project "node_modules" directory.

To run the tests:

npm test

The tests run against the CoffeeScript source files.

To generate the JavaScript files:

make build

The test suite is run online with Travis against Node.js version 0.6, 0.7, 0.8 and 0.9.
