how to upload and download excel file on client side local folder in angularjs?

I had the same problem and spend many hours find different solutions for AngularJS code,

You can do something like this using Blob.

<a download="content.txt" ng-href="{{ url }}">download</a>

in your controller:

var content = 'file content for example';

var blob = new Blob([ content ], { type : 'text/plain' });

$scope.url = (window.URL || window.webkitURL).createObjectURL( blob );

in order to enable the URL:

app = angular.module(...);

app.config(['$compileProvider',

function ($compileProvider) {

$compileProvider.aHrefSanitizationWhitelist(/^\s*(https?|ftp|mailto|tel|file|blob):/);

}]);
