TypeError: Cannot read property 'sheets' of undefined

See original GitHub issue

I got this error when I tested the parsing process from an excel file. Hope someone can help me with this

Not sure of the exact root cause, but opening the file in Excel and saving it again works.

Hi Everyone,

I reproduced this issue: Failed: Cannot read property ‘sheets’ of undefined

Configuration settings:

node - v: 14.16.0
“exceljs”: “^4.2.1”
test File: testFile.xlsx
Code:

const ExcelJS = require('exceljs');
const pageComparisonXLSXFilePath = './testFile.xlsx';
const workbook = new ExcelJS.Workbook();
await workbook.xlsx.readFile(pageComparisonXLSXFilePath); 
const worksheet = workbook.getWorksheet(1);
const rowC = worksheet.rowCount;
for (const row of worksheet.getRows(1, rowC)) {
  console.log(row.values);
}

Error raises during next line execution: await workbook.xlsx.readFile(pageComparisonXLSXFilePath);

Steps to reproduce: 1. Download file -> exec code -> exception: Failed: Cannot read property ‘sheets’ of undefined. but 2. If I open this file by MSExcel and then simply save this file and close it -> code executes correctly.

Could you help me?

Regards, Sergei.
