I have been trying to use and following the examples from this library: https://www.npmjs.com/package/exceljs#create-a-workbook I am using it on Angular 5. I always get an error graceful-fs.js:166 Uncaught TypeError: Cannot read property 'prototype' of undefined at patch (graceful-fs.js:166) From these lines of my code: import * as Excel from 'exceljs'; export class ExcelHandler { public testExcelJs() { var workBook: Excel.Workbook; var workSheet: Excel.Worksheet; workBook = new Excel.Workbook(); workSheet = workBook.addWorksheet(sheetName); } } Thanks. Seems the npm example is given in node

Modify existing Excel File using node.js

Is there any way to modify existing excel file in node.js? I've looked into exceljs but it does not provide any functionality that will just modify the existing data. It seems like it will write to a new stream. Or did I miss something on exceljs? Thanks in advance. exceljs does let you modify Excel spreadsheets. Here's an example of reading in an existing spreadsheet and writing it back out to a different file: var Excel = require('exceljs'); var workbook = new Excel.Workbook(); workbook.xlsx.readFile('old.xlsx') .then(function() { var worksheet = workbook.getWorksheet(1); var row = worksheet
