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 (is really fast)
- 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.
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.
To learn how to use Papa Parse:
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.
For usage instructions, see the homepage and, for more detail, the documentation.
Papa Parse is under test. Download this repository, run npm install, then npm test to run the tests.
