Let’s get started.

Laravel Installation

We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.

Here is the command to create a laravel project-

$ composer create-project --prefer-dist laravel/laravel blog

To start the development server of Laravel –

$ php artisan serve


Assuming laravel already installed inside your system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.


Install maatwebsite/excel Package & Configuration

Open project into terminal and run this composer command to install package.

$ composer require maatwebsite/excel

After package installation, open app.php file from /config folder. Search for providers and aliases add these –

'providers' => [

'aliases' => [
         'Excel' => Maatwebsite\Excel\Facades\Excel::class,

Create Import Class

Once you will install the above package. You will see we should have a command available in artisan list i.e make:import. We will use this command to create import class.

Open terminal and run this command –

$ php artisan make:import UsersImport --model=User

It will create a file UsersImport.php file inside /app/Imports folder.

Open UsersImport.php and write this complete code into it.

namespace App\Imports;
use App\Models\User;
use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\ToCollection;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
use Illuminate\Support\Facades\Validator;
class UsersImport implements ToCollection, WithHeadingRow
    * @param array $row
    * @return \Illuminate\Database\Eloquent\Model|null
    public function collection(Collection $rows)
         Validator::make($rows->toArray(), [
             '*.name' => 'required',
             '*.email' => 'required',
             '*.password' => 'required',
        foreach ($rows as $row) {
                'name' => $row['name'],
                'email' => $row['email'],
                'password' => bcrypt($row['password']),

Create Controller

Next, we need to create a controller file.

$ php artisan make:controller DataImportController

It will create a file DataImportController.php at /app/Http/Controllers folder.

Open DataImportController.php and write this complete code into it.


namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Imports\UsersImport;
use Maatwebsite\Excel\Facades\Excel;

class DataImportController extends Controller
     * Write code on Method
     * @return response()
    public function index()
        return view('user-import');

     * Write code on Method
     * @return response()
    public function store()
        Excel::import(new UsersImport, request()->file('file'));

        return back()->with('success', 'User Imported Successfully.');

Create Route

Open web.php from /routes folder and add these route into it.


use App\Http\Controllers\DataImportController;

Route::get('users-import', [DataImportController::class, 'index']);
Route::post('import', [DataImportController::class, 'store'])->name('import');


Create Blade Layout File

Go to /resources/views folder and create a file with name user-import.blade.php

Open user-import.blade.php and write this complete code into it.

                              {{ $error }} <br>
                    @if (Session::has('success'))
                        <div class="row">

                                <h5>{!! Session::get('success') !!}</h5>   
                    <input type="file" name="file" class="form-control">
                    <button class="btn btn-success">Submit</button>


Application Testing

Run this command into project terminal to start development server,
