Parse CSV with JavaScript
========================================

Papa Parse is the fastest in-browser CSV (or delimited text) parser for JavaScript. It is reliable and correct according to [RFC 4180](https://tools.ietf.org/html/rfc4180), 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](https://www.npmjs.com/package/papaparse). It
can be installed with the following command:

    npm install papaparse

If you don't want to use npm, [papaparse.min.js](https://unpkg.com/papaparse@latest/papaparse.min.js) can be downloaded to your project source.

Usage
-----

    import Papa from 'papaparse';

    Papa.parse(file, config);

Papa Parse for Node
--------------------

Papa Parse can parse a [Readable Stream](https://nodejs.org/api/stream.html#stream_readable_streams) instead of a [File](https://www.w3.org/TR/FileAPI/) 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](https://nodejs.org/api/stream.html#stream_readable_streams) 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)`.
