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, 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.

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.
