FileSaver.js saveAs(Xlsx)

Question

I am using filesaver.js to export my div (with multiple tables) to excel. I am able to export it as XLS using the code below.

var blob = new Blob([document.getElementById('exportable').innerHTML], {
    type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8"
});
saveAs(blob, "Test Report using FileSaver.xls");

However, I want to export my div to XLSX. Can anyone help? I have tried changing the MIME type to XLSX, but didn't help.

Update W3C does not implemented .xlsx so the browsers too. But you can use alsql a js library which export data as a valid .xlsx here is the jsfiddle or run below code

function myCtrl($scope) {
    $scope.exportData = function () {
        alasql('SELECT * INTO XLSX("Report.xlsx",{headers:true}) FROM ?',[$scope.items]);
    };
    
    $scope.items = [{
        name: "John Smith",
        email: "j.smith@example.com",
        dob: "1985-10-10"
    }, {
        name: "Jane Smith",
        email: "jane.smith@example.com",
        dob: "1988-12-22"
    }, {
        name: "Jan Smith",
        email: "jan.smith@example.com",
        dob: "2010-01-02"
    }, {
        name: "Jake Smith",
        email: "jake.smith@exmaple.com",
        dob: "2009-03-21"
    }, {
        name: "Josh Smith",
        email: "josh@example.com",
        dob: "2011-12-12"
    }, {
        name: "Jessie Smith",
        email: "jess@example.com",
        dob: "2004-10-12"
    }];
};
