// Read an Excel file
const workbook = XLSX.readFile('data.xlsx');
const sheetName = workbook.SheetNames[0];
const worksheet = workbook.Sheets[sheetName];

// Convert sheet to JSON
const data = XLSX.utils.sheet_to_json(worksheet);
console.log(data);

// Write JSON data to a new Excel file
const newWorkbook = XLSX.utils.book_new();
const newWorksheet = XLSX.utils.json_to_sheet(data);
XLSX.utils.book_append_sheet(newWorkbook, newWorksheet, 'Sheet1');
XLSX.writeFile(newWorkbook, 'output.xlsx');
