我尝试在Excel文件中导出amcharts图表数据，但没有导出并且没有错误显示 而不是XLSX格式的其他格式文件，如csv导出

var chart = AmCharts.makeChart("chartdiv",{
    "type": "serial","theme": "light","dataProvider": [{
        "country": "USA","visits": 2025

    },{
        "country": "Brazil","visits": 395
    }],"valueAxes": [{
        "gridColor": "#FFFFFF","gridAlpha": 0.2,"dashLength": 0
    }],"gridAboveGraphs": true,"startDuration": 1,"graphs": [{
        "balloonText": "[[category]]: <b>[[value]]</b>","fillAlphas": 0.8,"lineAlpha": 0.2,"type": "column","valueField": "visits"
    }],"chartCursor": {
        "categoryBalloonEnabled": false,"cursorAlpha": 0,"zoomable": false
    },"categoryField": "country","categoryAxis": {
        "gridPosition": "start","gridAlpha": 0,"tickPosition": "start","tickLength": 20
    },"export": {
        "enabled": true,"menu": [{
            "class": "export-main","menu": [{
                "label": "Excel","menu": ["XLSX","CSV"]
            }]
        }],}
});

使用此代码导出到csv成功，但在XLSX formate中不成功，并且不显示任何错误
