How to insert data into merged cell of an existing Excel file? #726
Description
Is there a way to insert data into a merged cell of an existing Excel file?
I am trying to do something like this:
const workbook = new Excel.Workbook();
workbook.xlsx.readFile('invoice А.xlsx')
.then(function() {
let worksheet = workbook.getWorksheet(1);
let row = worksheet.getRow(26);
row.getCell(2).value = 15;
row.commit();
return workbook.xlsx.writeFile('newInvoice.xlsx');
})
The error message is TypeError: Cannot read property 'getRow' of undefined.
