Angular in Excel Import

I am trying to implement a function to get the value of a table from an Excel file in html.

In my excel-function.html I have:

<script src="http://ift.tt/1uFAqid" type="text/javascript"></script>
<div ng-controller="myCtrl">
    <button ng-click="exportData()" ng-show="(items|filter:{selected: true}).length">Export</button>
    <br />
    <table width="100%">
            <thead>
                <tr>
                    <th></th>
                    <th>Name</th>
                    <th>Date</th>
                    <th>Terms</th>
                </tr>
            </thead>
            <tbody>
                <tr ng-repeat="item in items">
                    <td><input type="checkbox" ng-model="item.selected" /></td>
                    <td>{{item.Name}}</td>
                    <td>{{item.Date}}</td>
                    <td><span ng-repeat="term in item.Terms">{{term}}{{!$last?', ':''}}</span></td>
                </tr>
            </tbody>
        </table>
    <div id="exportable" style="display:none">
        <table width="100%">
            <thead>
                <tr>
                    <th>Name</th>
                    <th>Date</th>
                    <th>Terms</th>
                </tr>
            </thead>
            <tbody>
                <tr ng-repeat="item in items|filter:{selected: true}">
                    <td>{{item.Name}}</td>
                    <td>{{item.Date}}</td>
                    <td><span ng-repeat="term in item.Terms">{{term}}{{!$last?', ':''}}</span></td>
                </tr>
            </tbody>
        </table>
    </div>
</div>

In my excel-export.directive.js I have:

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

    $scope.importData = function () {
        var obj = xlsx(file);

    }

    $scope.items = [{
        "Name": "ANC101",
            "Date": "10/02/2014",
            "Terms": ["samsung", "nokia", "apple"]
    }, {
        "Name": "ABC102",
            "Date": "10/02/2014",
            "Terms": ["motrolla", "nokia", "iPhone"]
    }]
}

But I do not know how to get the excel file in the angular.

I'm not sure I should be put on how td reads the excel file.

How to import an Excel file, you wonder if you can put the value of the file in scope.
