Laravel Excel import export

Laravel Excel import export

Importing data from Excel sheet into our database and export data from the application into an Excel sheet are most often asked feature for a web application. These features enable us to perform batch import/export data by our web application. In Laravel, we can make excel import/export features easily with laravel maatwebsite/excel package. If you are looking for a step by step tutorial on how you can make excel import/export features in your application then it's for you. In this post, I'll show you a step by step guide for making excel import/export features in Laravel by using maatwebsite/excel laravel package with validation.

 

Steps for Laravel Excel Import-Export

  1. Install a new Laravel Framework instance
  2. Setup the database config & model.
  3. Install Laravel maatwebsite/excel package
  4. Make an Import class for import data.
  5. Make an Export class for export data
  6. Make a controller for handle excel data import or export

 

Install a new Laravel Framework instance

The first step, we need a fresh Laravel Framework instance. If you have already an application installed then skip this step. Let's do that by composer command.

composer create-project laravel/laravel laravel-import-export

 

Setup the database config & model

In this step, we'll set up our database configuration in the .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel-import-export
DB_USERNAME=root
DB_PASSWORD=

 

Now make a model. Here we'll make a contact model for our contacts table. Our contacts table contains id, name, phone, email fields.

<?php namespace App;

use Illuminate\Database\Eloquent\Model;

class Contact extends Model {
	public $timestamps = false;
        protected $fillable = ['name', 'phone', 'email'];
} 

 

Install Laravel maatwebsite/excel package

Now install the Laravel maatwebsite/excel version 3.1 package via composer command.

composer require maatwebsite/excel

This package has auto-discovery features so you don't need to add the service provider manually.

 

Make an Import class for import data.

Now we have to make an Import class for importing data into our database from Excel sheet via our contact model. The maatwebsite/excel package provides useful command to make the class easily. Let's do that.

php artisan make:import ContactsImport --model=Contact

with this command, a Contact import class will create in the app/Imports directory.

<?php

namespace App\Imports;

use App\Contact;
use Illuminate\Support\Facades\Hash;
use Maatwebsite\Excel\Concerns\ToModel;

class ContactsImport implements ToModel
{
    /**
     * @param array $row
     *
     * @return Contact|null
     */
    public function model(array $row)
    {
        return new Contact([
           'name'   => $row[0],
           'phone'  => $row[1], 
           'email'  => $row[2]
        ]);
    }
}

 

Make an Export class for export data

For export data from our database to Excel sheet, we need to make an Export class via command line.

php artisan make:export ContactsExport --model=Contact

By this command, a class file will create in app/Exports directory.

<?php

namespace App\Exports;

use App\Contact;
use Maatwebsite\Excel\Concerns\FromCollection;

class ContactsExport implements FromCollection
{
    public function collection()
    {
        return Contact::all();
    }
}

 

Make a controller for handle excel data import or export

Now the final part where we'll handle how we'll export or import data and what will be the logic goes to. Let's make a controller by artisan make command.

php artisan make:controller ContactController

 

Handle Excel data import

To import data from excel sheet, make an import method inside the contact controller. In this import method, we'll validate our request file and code for import the excel sheet data.

<?php

use App\Imports\ContactsImport;
use Maatwebsite\Excel\Facades\Excel;
use App\Http\Controllers\Controller;

class ContactsController extends Controller 
{
    public function import(Request $request) 
    {
        $this->validate($request, [
            'file' => 'required|file|mimes:xls,xlsx'
        ]);

  	$file = $request->file('file');
        Excel::import(new ContactsImport, $file);
        return redirect()->back()->with('success', 'All data successfully imported!');
    }
}

 

Handle Excel data export

With the data export feature, we can export our table data into an excel sheet very easily. For that, make an export method inside the contact controller and do code for model data export into an excel sheet.

<?php

namespace App\Http\Controllers;

use App\Exports\ContactsExport;
use Maatwebsite\Excel\Facades\Excel;

class ContactController extends Controller 
{

    public function export() 
    {
        return Excel::download(new ContactsExport, 'contacts.xlsx');
    }
}
