Angular.js

Angular.js + AlaSQL

You can use AlaSQL together with Angular.js framework by including it together with XLSX.js

import * as alasql from 'alasql';
import * as XLSX from 'xlsx';
alasql['utils'].isBrowserify = false;
alasql['utils'].global.XLSX = XLSX;

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

See a 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
        }); 
    };

NG2

Steps for a working AlaSQL configuration inside an NG2 project are:

1. npm install alasql --save
2. optional for XLSX export: npm install xlsx --save
3. add the javascript dependencies inside the .angular-cli.json file of your project

"scripts": [
    "../node_modules/alasql/dist/alasql.min.js",
    "../node_modules/xlsx/dist/xlsx.core.min.js"
],

4. next import into one of your components where you woudl like to use the alasql function (not inside app-module.ts) the AlaSQL dependency. import * as alaSQLSpace from 'alasql';
5. and if you would like to test your code, you can add this test block from jsfiddle: into your component.

public testAlaSQLExcelExport(): void {
   var data1 = [{ a: 1, b: 10 }, { a: 2, b: 20 }];
   var data2 = [{ a: 100, b: 10 }, { a: 200, b: 20 }];
   var opts = [{ sheetid: 'Good', header: true }, { sheetid: 'Two', header: false }];
   var res = alasql('SELECT INTO XLSX("MyAwesomeData.xlsx",?) FROM ?', [opts, [data1, data2]]);
}

6. now if you run ng serve the project will compile without any errors or warnings and if the testAlaSQLExcelExport() function is used you can see that the excel file will be exported inside your browser.
