Streaming csv parser inspired by binary-csv that aims to be faster than everyone else.

npm install csv-parser

csv-parser can convert CSV into JSON at at rate of around 90,000 rows per second (perf varies with data, try bench.js with your data).

Usage

Simply instantiate csv and pump a csv file to it and get the rows out as objects

You can use csv-parser in the browser with browserify

var csv = require('csv-parser')
 
fs.createReadStream('some-csv-file.csv')
  .pipe(csv())
  .on('data', function(data) {
    console.log('row', data)
  })

The data emitted is a normalized JSON object

The csv constructor accepts the following options as well

var stream = csv({
  raw: false,    // do not decode to utf-8 strings 
  separator: ',', // specify optional cell separator 
  newline: '\n' // specify a newline character 
})

Command line tool

There is also a command line tool available. It will convert csv to line delimited JSON.

npm install -g csv-parser

Open a shell and run

$ csv-parser --help # prints all options
$ printf "a,b\nc,d\n" | csv-parser # parses input
