You can modify excel, below is the example.

var Excel = require('exceljs');
async function excelOp() {
    let workbook = new Excel.Workbook();
    workbook = await workbook.xlsx.readFile('question_39869739.xlsx'); // replace question_39869739.xls with your file
    let worksheet = workbook.getWorksheet('sheetname'); // replace sheetname with actual sheet name
    worksheet.getRow('rowNumber').getCell('cellNumber').value = 350; // replace rowNumber and cellNumber with the row and cell you want to modify
    workbook.xlsx.writeFile('question_50508131.xlsx');
}

excelOp();
