js插件，快速解析csv文件

Parse CSV with JavaScript ======================================== Papa Parse is the [fastest](http://jsperf.com/javascript-csv-parsers/4) 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 ([is really fast](http://jsperf.com/javascript-csv-parsers/3)) - 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 Papa Parse has **no dependencies** - not even jQuery. Homepage & Demo ---------------- - [Homepage](http://papaparse.com) - [Demo](http://papaparse.com/demo) To learn how to use Papa Parse: - [Documentation](http://papaparse.com/docs) 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. Additionally, [Rich Harris](https://github.com/Rich-Harris) forked this project to make **[Baby Parse](https://github.com/Rich-Harris/BabyParse)** which runs in Node.js environments. ```bash $ npm install babyparse ``` [Baby Parse on npm registry](https://www.npmjs.org/package/babyparse) Use it just like Papa Parse. However: - Files are not supported; strings only (you can use Node's file facilities to load file contents yourself) - Some config options are unavailable: - worker - download (you can use Node's network facilities to download files yourself) - encoding - chunk Otherwise, Baby Parse has nearly all the same functionality as Papa Parse 4.0, including the `unparse()` utility.
