PAPA PARSE

Papa Parse is a powerful, in-browser CSV parser for the big boys and girls :)
If you do need easy CSV parsing and conversion back to CSV, take a look at it!

// Parse CSV string
var data = Papa.parse(csv);

// Convert back to CSV
var csv = Papa.unparse(data);

// Parse local CSV file
Papa.parse(file, {
	complete: function(results) {
		console.log("Finished:", results.data);
	}
});

// Stream big file in worker thread
Papa.parse(bigFile, {
	worker: true,
	step: function(results) {
		console.log("Row:", results.data);
	}
});

// Parse CSV string

var data = Papa.parse(csv);

// Convert back to CSV

var csv = Papa.unparse(data);

// Parse local CSV file

Papa.parse(file, {

complete: function(results) {

console.log("Finished:", results.data);

}

});

// Stream big file in worker thread

Papa.parse(bigFile, {

worker: true,

step: function(results) {

console.log("Row:", results.data);

}

});

ABOUT

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

USAGE

I am currently using it to quickly parse Adobe Audition CSV marker files and prepare them for storage for my podcast.
