var output_file_name = "out.csv";
var stream = XLSX.stream.to_csv(worksheet);
stream.pipe(fs.createWriteStream(output_file_name));
nodejs write JSON stream to screen (click to show)
/* to_json returns an object-mode stream */
var stream = XLSX.stream.to_json(worksheet, {raw:true});
/* the following stream converts JS objects to text via JSON.stringify */
var conv = new Transform({writableObjectMode:true});
conv._transform = function(obj, e, cb){ cb(null, JSON.stringify(obj) + "\n"); };
stream.pipe(conv); conv.pipe(process.stdout);
