Javascript JSON到Excel文件下载
我有Json数据，我需要使用javascript将Json数据转换为Excel文件 参考网址： 我正在使用以下代码：Javascript JSON到Excel文件下载,javascript,json,Javascript,Json,我有Json数据，我需要使用javascript将Json数据转换为Excel文件 参考网址： 我正在使用以下代码： function JSONToTSVConvertor(JSONData, ReportTitle, ShowLabel, myTemplateName){ //If JSONData is not an object then JSON.parse will parse the JSON string in an Object var arrData = ty
function JSONToTSVConvertor(JSONData, ReportTitle, ShowLabel, myTemplateName){
//If JSONData is not an object then JSON.parse will parse the JSON string in an Object
var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
var TSV = '';
//Set Report title in first row or line
//TSV += ReportTitle + '\r\n\n';
//This condition will generate the Label/Header
if (ShowLabel) {
var row = "";
//This loop will extract the label from 1st index of on array
for (var index in arrData[0]) {
//Now convert each value to string and tab-seprated
row += index + ' ';
}
row = row.slice(0, -1);
//append Label row with line break
TSV += row + '\r\n';
}
//1st loop is to extract each row
for (var i = 0; i < arrData.length; i++) {
var row = "";
//2nd loop will extract each column and convert it in string tab-seprated
for (var index in arrData[i]) {
row += '"' + arrData[i][index] + '" ';
}
row.slice(0, row.length - 1);
//add a line break after each row
TSV += row + '\r\n';
}
if (TSV == '') {
alert("Invalid data");
return;
}
var blob = new Blob([TSV], {type: "data:text/tsv;charset=utf-8"});
//Generate a file name
var fileName = myTemplateName;
//this will remove the blank-spaces from the title and replace it with an underscore
fileName += ReportTitle.replace(/ /g,"_");
saveAs(blob, ""+fileName+".tsv");
}
函数JSONToTSVConvertor（JSONData、ReportTitle、ShowLabel、myTemplateName）{
//如果JSONData不是对象，那么JSON.parse将解析对象中的JSON字符串
var arrData=typeof JSONData！=“object”？JSON.parse（JSONData）：JSONData；
var TSV=“”；
//在第一行或第一行设置报表标题
//TSV+=ReportTitle+'\r\n\n'；
//此条件将生成标签/标题
如果（显示标签）{
var行=”；
//此循环将从数组的第一个索引中提取标签
对于（arrData[0]中的var索引）{
//现在，将每个值转换为字符串和制表符
行+=索引+“”；
}
row=row.slice（0，-1）；
//用换行符追加标签行
TSV+=行+'\r\n'；
}
//第一个循环是提取每一行
对于（变量i=0；i谢谢 Excel是一种非常复杂的格式，有许多版本。如果您真的需要这样做，我将调查其他人编写的一些JavaScript库。在谷歌上搜索“javascript excel writer”以查看一些示例。CSV，如前所述，就是excel文件本身。但是，在许多地区，上面的脚本生成的csv被错误地打开，excel将所有内容都放在一个单元格中。对原始脚本的小修改有帮助：只需将标题替换为“sep=，” 此处有更改的工作示例：
我花了一些时间来弄明白这一点，因此回答旧的问题以帮助其他人节省一些时间。我知道回答有点晚，但我找到了一个很好的
angularng json export excel<button ng-json-export-excel data="dataList" report-fields="{'uesr.username': 'Heder 1', keyjson2: 'Header 2', keyjson3: 'Head 3'}" filename =" 'export-excel' " separator="," class="css-class"></button>
我创建了一个类，用于将json数据导出到excel文件。如果在我的代码中进行一些有成效的编辑，我会很高兴的 只需在JS库中添加该类并调用：
