How to create an Excel File with Node.js?

To create an Excel File with Node.js, we use the xlsx module.

For instance, we write

const XLSX = require("xlsx");

const wb = XLSX.utils.book_new();
XLSX.writeFile(wb, "out.xlsx");

to call the book_new method to create a new Excel workbook.

Then we call writeGile to write the wb workbook to out.xlsx.
