Javascript JSON 到 Excel 文件下载

Question

我有 Json 数据，我需要使用 javascript 将 json 数据转换为 Excel 文件，

引用网址:http://jsfiddle.net/hybrid13i/JXrwM/

我正在使用这段代码:

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 = 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");
}

此示例代码适用于 csv 和 tsv 格式。我需要 Excel 格式，我不认为有任何想法请帮助我。请建议一些示例代码。谢谢...

我使用了以下代码 Javascript JSON 到 Excel 或 CSV 文件下载

仅更改文件扩展名(reports.xlsx 或 reports.CSV)

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.13.1/xlsx.full.min.js"></script> 
<script>
    function ExportData()
    {
            filename='reports.xlsx';
       data=[{Market: "IN", New Arrivals: "6", Upcoming Appointments: "2", Pending - 1st Attempt: "4"},
            {Market: "KS/MO", New Arrivals: "4", Upcoming Appointments: "4", Pending - 1st Attempt: "2"},
            {Market: "KS/MO", New Arrivals: "4", Upcoming Appointments: "4", Pending - 1st Attempt: "2"},
            {Market: "KS/MO", New Arrivals: "4", Upcoming Appointments: "4", Pending - 1st Attempt: "2"}]
        var ws = XLSX.utils.json_to_sheet(data);
        var wb = XLSX.utils.book_new();
        XLSX.utils.book_append_sheet(wb, ws, "People");
        XLSX.writeFile(wb,filename);
     }
</script>
