// Create a new workbook
let wb = XLSX.utils.book_new();

// Add a new worksheet
let ws_data = [['Name', 'Age'], ['Alice', 30], ['Bob', 25]];
let ws = XLSX.utils.aoa_to_sheet(ws_data);
XLSX.utils.book_append_sheet(wb, ws, 'Sheet1');

// Write the workbook to a file
XLSX.writeFile(wb, 'output.xlsx');
