### Streaming Write The streaming write functions are available in the `XLSX.stream` object. They take the same arguments as the normal write functions but return a Readable Stream. They are only exposed in NodeJS. - `XLSX.stream.to_csv` is the streaming version of `XLSX.utils.sheet_to_csv`. - `XLSX.stream.to_html` is the streaming version of `XLSX.utils.sheet_to_html`. - `XLSX.stream.to_json` is the streaming version of `XLSX.utils.sheet_to_json`. <details> <summary><b>nodejs convert to CSV and write file</b> (click to show)</summary> ```js var output_file_name = "out.csv"; var stream = XLSX.stream.to_csv(worksheet); stream.pipe(fs.createWriteStream(output_file_name)); ``` </details> <details> <summary><b>nodejs write JSON stream to screen</b> (click to show)</summary> ```js /* 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); ``` </details> <https://github.com/sheetjs/sheetaki> pipes write streams to nodejs response.
