JS 根据Json数据导出Excel

//导出Excel
function JSONToExcelConvertor(JSONData, FileName) {
    //先转化json
    var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
    var excel = '<table>';
    var row = "<tr>";
    //设置表头
    var keys = Object.keys(JSONData[0]);
    keys.forEach(function (item) {
        row += "<td>" + item + '</td>';
    });
    //换行
    excel += row + "</tr>";
    //设置数据
    for (var i = 0; i < arrData.length; i++) {
        var row = "<tr>";
        for (var index in arrData[i]) {
            console.log(arrData[i][index]);
            //var value = arrData[i][index] === "." ? "" : arrData[i][index];
            row += '<td>' + arrData[i][index] + '</td>';
        }
        excel += row + "</tr>";
    }
