Cannot read property 'cells' of undefined

Hi ! I just want to try before coding and it’s not working … I have this code :

var Excel = require('exceljs');
var filename = './test.xlsx';

var workbook = new Excel.Workbook();
workbook.xlsx.readFile(filename)
    .then(function() {
        // use workbook
        var worksheet = workbook.getWorksheet('Dataset1');
        worksheet.eachRow(function(row, rowNumber) {
            console.log('Row ' + rowNumber + ' = ' + JSON.stringify(row.values));
        });
    });

But I have this error :

Cannot read property ‘cells’ of undefined

hi, @hazemsamoaa . inboundWorkbook.getWorksheet(1); This is probably where the problem lies, try to replace id with sheet name. Step into inboundWorkbook.getWorksheet(1) and wath this._worksheets, you’ll find that you have several sheets but no one’s id is 1.

i have same issue! but i can solved it

i create new workbook and copy content from old excel file to new workbooks and save it to .xlsx

i think my issue occur from older version of excel (you can not convert from xls to xlsx by using save as or online convert because i tried it! not work). my issue same like #652
