Why my excel is corrupt when adding data?

This code is supposed to add "ABC" in B3, but when writing the document, its size goes to 0ko (original is ~200ko) and Excel refuse to open it up.

const modele = "./myexcel.xlsx"

var workbook = new excel.Workbook();
workbook.xlsx.readFile(modele)
.then(function() {
    var worksheet = workbook.getWorksheet('Personnel');

    worksheet.getCell('B3').value = "ABC";
    
    return workbook.xlsx.writeFile(modele)

});

I don't want to create a new sheet but to write in an existing one

I tried using stream, writing in a new file and different version of this code but it doesn't seems to work.

I'm using ExcelJS before for the same purpose and it work.

The cell B3 is in a table I want to add a lot of data in.
