Angular.js

Angular.js + AlaSQL

You can use AlaSQL together with Angular.js framework. Please include the file normally and not via requireJS. Please include alasql before requireJS to avoid issue of "Mismatched anonymous define() module". This issue is with requireJS.

    $scope.exportData = function () {
        alasql('SELECT * INTO XLSX("john.xlsx",{headers:true}) FROM ?',[$scope.items]);
    };

See simple example in jsFiddle.

In more detail

If AlaSQL recognize Angular.js it removes $$hashKey artefacts from the exporting arrays.

To remove other artefact fields you can use [REMOVE COLUMNS](Remove Columns) clause.

For example, you can integrate these libraries it for import or export data files from MS Excel.

Export file to Excel

HTML:

    <button ng-if="$root.appInfo.model.rows"     // show excel icon only if there are rows in the grid 
        class="btn"ng-click="$root.exportData()">
    </button> 

Controller:

    $rootScope.exportData = function () {
        alasql('SELECT * INTO XLSX("list.xlsx",{headers:true}) FROM ?', 
              [$rootScope.appInfo.model.rows]);   
    };

Import data from file in client computer

Unfortunately, we cannot use ng-change because the input needs to be bound (ng-model), but it seems that type=file inputs are not supported for binding in Angular.js, so we can switch to ng-mouseleave and it worked, though we had to check in the function that a file had been chosen.

HTML:

    <input type="file" ng-mouseleave="loadFile($event)" />

Controller:

    $rootScope.loadFile = function (event) {
        if (event.fromElement.files.length==0) {
            return(false);   // leave in case no file was chosen
        };
        alasql('SELECT * FROM FILE(?,{headers:true})', [event], function (data) {
            $rootScope.eData = data;     //  eData contains the JSON representation of the Excel sheet rows
        }); 
    };
