How does xlsx.default work?

xlsx.default is the default export of the "xlsx" module, which provides a set of functions for reading and writing Excel files in various formats, including XLSX, XLS, and CSV. The module uses a parser and writer to convert Excel files to and from JavaScript objects. The default export provides a convenient way to access the main functionality of the module. It supports reading and writing data, styling, formatting, and more.

const XLSX = require("xlsx");

// Load the workbook
const workbook = XLSX.readFile("example.xlsx");

// Select the first worksheet
const worksheet = workbook.Sheets[workbook.SheetNames[0]];

// Convert the worksheet to a JSON object
const json = XLSX.utils.sheet_to_json(worksheet);

console.log(json);

This code reads an Excel file named "example.xlsx" using the XLSX.readFile() method. It then selects the first worksheet in the workbook and converts it to a JSON object using the XLSX.utils.sheet_to_json() method. Finally, it logs the resulting JSON object to the console.
