Hi, guys! Thank you for you open source library. In the last week I had task to export some data in excel document. I use this small code: ``` const Excel = require('exceljs'); const Readable = require('stream').Readable; const Writable = require('stream').Writable; const stream2n = new Writable(); stream2n.result = []; stream2n._write = function (chunk, enc, next) { this.result.push(chunk); }; const stream1n = new Readable(); stream1n._read = function () { stream1n.push(stream2n.result.shift() || null); }; const workbook = new Excel.Workbook(); const pageName = 'Page name'; workbook.addWorksheet(pageName); workbook.getWorksheet(pageName).addRow([1, 2, 3, 4, 5]); let promise2 = new Promise((resolve, reject) => { workbook.xlsx.write(stream2n).then(() => { setTimeout(() => console.log('RESOLVED!'), 500); resolve(true); }); }); console.log('AT THE END'); ``` It works nice, but now I have task to import doc as csv file. I change just one line: ` workbook.xlsx.write(stream2n).then(() => {` I change with: ` workbook.csv.write(stream2n).then(() => { ` But now read stream will never closed. Have you any advice how I can fix it? It seems that this is the bug of exceljs. Thanks!
