使用js-xlsx解析Excel中的数据

Question

我正在使用js-xlsx，如果需要，这里是我的excel sheet的链接。我使用了以下代码：

/* set up XMLHttpRequest */
var url = "Test.xlsx";
var oReq = new XMLHttpRequest();
oReq.open("GET", url, true);
oReq.responseType = "arraybuffer";

oReq.onload = function(e) {
var arraybuffer = oReq.response;

/* convert data to binary string */
var data = new Uint8Array(arraybuffer);
var arr = new Array();
for(var i = 0; i != data.length; ++i) arr[i] =String.fromCharCode(data[i]);
var bstr = arr.join("");

/* Call XLSX */
var workbook = XLSX.read(bstr, {type:"binary"});

/* DO SOMETHING WITH workbook HERE */
var first_sheet_name = workbook.SheetNames[0];
/* Get worksheet */
var worksheet = workbook.Sheets[first_sheet_name];

console.log(XLSX.utils.sheet_to_json(worksheet,{raw:true}));
}
oReq.send();

在控制台loge中，我得到以下输出：

(3) […]​0: Object { FirstName: "Mayuresh", MiddleName: "Dinkar ", LastName: "Joshi", … }​1: Object { FirstName: "Arun", MiddleName: "Vikas", LastName: "Pathak", … }​2: Object { FirstName: "Narendra", MiddleName: "Damodardas", LastName: "Modi", … }​length: 3​<prototype>: Array []

我肯定不知道如何访问这些数据。我不知道该怎么称呼它。我尝试过arr.length，但它只返回1，它应该返回3。JS文件返回的长度是3，但我不确定它是从哪里提取的。我只需要访问那个数组。谢谢

看起来它起作用了。试试这个来看看...

let worksheet = workbook.Sheets[first_sheet_name];
let objects = XLSX.utils.sheet_to_json(worksheet,{raw:true});
let names = objects.map(object => `${object.FirstName} ${object.LastName}`);
console.log(names);
