You can use exceljs to work with excels. You can do something like this:

const Excel = require('exceljs');
const workbook = new Excel.Workbook();

workbook.xlsx.readFile('path to file')
    .then(() => {
        const worksheet = workbook.getWorksheet(1);
        const row = worksheet.getRow(15);
        row.getCell(1).value = 'pass_new_value';
        row.commit();
        return workbook.xlsx.writeFile('path-to-new-file');
    }).catch((e) => {
       console.log(e);
    })

I would suggest you get all the data first and then write to the sheet instead of updating one column at a time.
