Parsing a xlsx from file/buffer
var xlsx = require('async-xlsx');
// parses a file synchronously (may not be immediately available!)
var obj = xlsx.parse(__dirname + '/myFile.xlsx');
// parses a buffer
var obj = xlsx.parse(fs.readFileSync(__dirname + '/myFile.xlsx'));
// parse file asynchronously, returns an object
xlsx.parseFileAsync(__dirname + '/myFile.xlsx', {options}, function(parsedObject){
// Data is now ready
});
// Do something else while file is being parsed and come back when file is ready...
Building a plist from an object
var xlsx = require('async-xlsx');
var data = [[1,2,3],[true, false, null, 'sheetjs'],['foo','bar',new Date('2014-02-19T14:30Z'), '0.3']];
var buffer = xlsx.build([{name: "mySheetName", data: data}]); // returns a buffer
