Hey guys! Ever needed to export data from your Laravel app to Excel, complete with those neat column headers? It’s a pretty common task, and luckily, Laravel makes it straightforward. Let’s dive into how you can achieve this, step by step, making sure it’s super clear and easy to follow.

Setting Up Your Laravel Project

First things first, make sure you have a Laravel project ready to go. If you don’t, you can quickly create one using the Laravel installer. Open up your terminal and run:

composer create-project --prefer-dist laravel/laravel excel_export_example
cd excel_export_example

This will create a new Laravel project named excel_export_example. Once that's done, navigate into your project directory.

Next, we need to install the maatwebsite/excel package, which is a fantastic library for handling Excel exports and imports in Laravel. Run the following command:

composer require maatwebsite/excel

After the package is installed, you should publish the configuration file. This allows you to tweak the default settings if needed. Execute this command:

php artisan vendor:publish --tag=excel

Now you’re all set with the basic setup! Let’s move on to creating the export class.

Creating the Export Class

The heart of our Excel export is the export class. This class will define how our data is structured and which headers to include. Create a new export class using the Artisan command:

php artisan make:export UsersExport --model=User

This command generates a file named UsersExport.php in the app/Exports directory. Open this file, and you'll see a basic class structure. We need to modify this to include our headers and data.

Here’s how your UsersExport.php might look:

namespace App\Exports;

use App\Models\User;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\WithHeadings;

class UsersExport implements FromCollection, WithHeadings
{
 public function collection()
 {
 return User::all();
 }

 public function headings(): array
 {
 return [
 'ID',
 'Name',
 'Email',
 'Created At',
 'Updated At',
 ];
 }
}

Let's break this down:

• namespace App\Exports;: This line defines the namespace for our export class.
• use App\Models\User;: We’re importing the User model to fetch data from the users table.
• use Maatwebsite\Excel\Concerns\FromCollection;: This interface requires us to define a collection() method, which returns the data we want to export.
• use Maatwebsite\Excel\Concerns\WithHeadings;: This interface requires us to define a headings() method, which returns an array of column headers.
• class UsersExport implements FromCollection, WithHeadings: This declares our class and implements the necessary interfaces.
• public function collection(): This method fetches all users from the database using User::all() and returns them as a collection.
• public function headings(): array: This method returns an array of strings, which will be used as the column headers in the Excel file.

Customizing Your Data and Headers:

You can customize the collection() method to fetch specific data, apply filters, or perform any other data manipulation you need. For example, if you only want to export users created in the last month, you could modify the method like this:

public function collection()
{
 return User::where('created_at', '>=', now()->subMonth())->get();
}

Similarly, you can customize the headings() method to include different headers or change their order. Just make sure the order of the headers matches the order of the data in your collection() method.

Creating the Controller Method

Now that we have our export class, we need a way to trigger the export. This is typically done through a controller method. Let’s create a new controller (if you don’t have one already) using the Artisan command:

php artisan make:controller ExportController

This will create a file named ExportController.php in the app/Http/Controllers directory. Open this file and add a method to handle the export:

namespace App\Http\Controllers;

use App\Exports\UsersExport;
use Maatwebsite\Excel\Facades\Excel;
use Symfony\Component\HttpFoundation\BinaryFileResponse;

class ExportController extends Controller
{
 public function export(): BinaryFileResponse
 {
 return Excel::download(new UsersExport, 'users.xlsx');
 }
}

Here’s what’s happening in this controller method:

• namespace App\Http\Controllers;: Defines the namespace for our controller.
• use App\Exports\UsersExport;: Imports our UsersExport class.
• use Maatwebsite\Excel\Facades\Excel;: Imports the Excel facade, which provides convenient methods for exporting data.
• use Symfony\Component\HttpFoundation\BinaryFileResponse;:
• public function export(): This method is responsible for triggering the Excel export.
• return Excel::download(new UsersExport, 'users.xlsx');: This line uses the Excel::download() method to generate the Excel file and return it as a download. The first argument is an instance of our UsersExport class, and the second argument is the filename for the exported file (users.xlsx).

Customizing the Filename:

You can customize the filename by changing the second argument of the Excel::download() method. For example, you could include the current date and time in the filename:

return Excel::download(new UsersExport, 'users_' . now()->format('Y-m-d_H-i-s') . '.xlsx');

Defining the Route

To access our export controller method, we need to define a route. Open the routes/web.php file and add the following route:

use App\Http\Controllers\ExportController;
use Illuminate\Support\Facades\Route;

Route::get('/export/users', [ExportController::class, 'export']);

This route maps the URL /export/users to the export method of our ExportController. Now, when you visit this URL in your browser, it will trigger the Excel export.

Testing the Export

Alright, time to see if all our hard work paid off! Start your Laravel development server using the Artisan command:

php artisan serve

This will start the server, usually on http://localhost:8000. Now, open your browser and visit http://localhost:8000/export/users. If everything is set up correctly, your browser should automatically download an Excel file named users.xlsx (or whatever filename you specified).

Open the downloaded file in Excel or any other spreadsheet program. You should see the data from your users table, complete with the column headers we defined in the UsersExport class.

Troubleshooting:

If you encounter any issues, double-check the following:

• Make sure you have the maatwebsite/excel package installed correctly.
• Verify that the namespace and class names are correct in your export class and controller.
• Ensure that the route is defined correctly and points to the correct controller method.
• Check your database connection and make sure you have data in the users table.

Advanced Customization

Using Query Builder

Instead of exporting all users, you might want to export a subset of users based on certain criteria. You can achieve this by using Laravel's query builder in the collection() method of your export class.

For example, to export only active users, you can modify the collection() method like this:

public function collection()
{
 return User::where('status', 'active')->get();
}

Styling the Excel File

The maatwebsite/excel package also allows you to style the exported Excel file. You can change the font, colors, and other formatting options. To do this, you need to implement the WithStyles interface in your export class.

Here’s an example of how to style the header row:

namespace App\Exports;

use App\Models\User;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\WithStyles;
use PhpOffice\PhpSpreadsheet\Worksheet\Worksheet;

class UsersExport implements FromCollection, WithHeadings, WithStyles
{
 public function collection()
 {
 return User::all();
 }

 public function headings(): array
 {
 return [
 'ID',
 'Name',
 'Email',
 'Created At',
 'Updated At',
 ];
 }

 public function styles(Worksheet $sheet)
 {
 return [
 // Style the header row as bold text.
 1 => ['font' => ['bold' => true]],
 ];
 }
}

In this example, we’re implementing the WithStyles interface and defining a styles() method. This method receives a Worksheet object, which represents the Excel sheet. We can then use this object to apply styles to different parts of the sheet. In this case, we’re making the first row (the header row) bold.

Using a View

For more complex layouts and formatting, you can use a view to generate the Excel content. This allows you to use Blade templates to define the structure and styling of your Excel file.

First, create a Blade view file (e.g., resources/views/exports/users.blade.php) with the following content:

<table>
 <thead>
 <tr>
 <th>ID</th>
 <th>Name</th>
 <th>Email</th>
 <th>Created At</th>
 <th>Updated At</th>
 </tr>
 </thead>
 <tbody>
 @foreach($users as $user)
 <tr>
 <td>{{ $user->id }}</td>
 <td>{{ $user->name }}</td>
 <td>{{ $user->email }}</td>
 <td>{{ $user->created_at }}</td>
 <td>{{ $user->updated_at }}</td>
 </tr>
 @endforeach
 </tbody>
</table>

Then, modify your export class to implement the FromView interface instead of FromCollection:

namespace App\Exports;

use App\Models\User;
use Illuminate\Contracts\View\View;
use Maatwebsite\Excel\Concerns\FromView;

class UsersExport implements FromView
{
 public function view(): View
 {
 return view('exports.users', [
 'users' => User::all()
 ]);
 }
}

In this example, we’re implementing the FromView interface and defining a view() method. This method returns a view, passing the users data to it. The view will then be rendered and exported to Excel.

Conclusion

So there you have it! Exporting Excel files with headers in Laravel is super manageable with the maatwebsite/excel package. Whether you need basic exports or more complex, styled reports, Laravel provides the tools to get the job done efficiently. Happy exporting, and remember to have fun coding!
