Papa Parse is the fastest in-browser CSV (or delimited text) parser for JavaScript. It is reliable and correct according to RFC 4180, and it comes with these features:

  • Easy to use
  • Parse CSV files directly (local or over the network)
  • Fast mode
  • Stream large files (even via HTTP)
  • Reverse parsing (converts JSON to CSV)
  • Auto-detect delimiter
  • Worker threads to keep your web page reactive
  • Header row support
  • Pause, resume, abort
  • Can convert numbers and booleans to their types
  • Optional jQuery integration to get files from <input type="file"> elements
  • One of the only parsers that correctly handles line-breaks and quotations

Papa Parse has no dependencies - not even jQuery.

Install

papaparse is available on npm. It can be installed with the following command:

npm install papaparse

If you don't want to use npm, papaparse.min.js can be downloaded to your project source.

Usage

import Papa from 'papaparse';

Papa.parse(file, config);
    
const csv = Papa.unparse(data[, config]);

Homepage & Demo

To learn how to use Papa Parse:

The website is hosted on Github Pages. Its content is also included in the docs folder of this repository. If you want to contribute on it just clone the master of this repository and open a pull request.

Papa Parse for Node

Papa Parse can parse a Readable Stream instead of a File when used in Node.js environments (in addition to plain strings). In this mode, encoding must, if specified, be a Node-supported character encoding. The Papa.LocalChunkSize, Papa.RemoteChunkSize , download, withCredentials and worker config options are unavailable.

Papa Parse can also parse in a node streaming style which makes .pipe available. Simply pipe the Readable Stream to the stream returned from Papa.parse(Papa.NODE_STREAM_INPUT, options). The Papa.LocalChunkSize, Papa.RemoteChunkSize , download, withCredentials, worker, step, and complete config options are unavailable. To register a callback with the stream to process data, use the data event like so: stream.on('data', callback) and to signal the end of stream, use the 'end' event like so: stream.on('end', callback).
