Laravel Import Inputted Data on JSON File and Download It

Hello Artisans, today I'll teach you about how you can create an json file from inputted data through <form>. As all of we know that json format is accepted by globally in each of every stack. So, it can be quite helpful to retrieve data in json file. So, let's see how we can accomplish our result with just few steps.

Note: Tested on Laravel 9.19

Create and Setup Controller

Frist, we'll create a controller called JsonFileController.php where we'll write our logic to create an json file first then put the request date into json file. So, fire the below command in terminal to generate controller first.

php artisan make:controller JsonFileController

Now we'll do add logic to our controller. See the below source code.

class JsonFileController extends Controller
    public function downloadJson(Request $request): \Symfony\Component\HttpFoundation\BinaryFileResponse
        $data = $request->except('_token');
        $json = json_encode($data);
        $file = Str::uuid().'.json';
        $path = public_path($file);
        file_put_contents($path, $json);
        return response()->download($path);

Define Routes

Now we'll add routes which will connect our <form> with our controller. So, let's add the below route to our web.php.

Route::post('download-json',[App\Http\Controllers\JsonFileController::class, 'downloadJson'])->name('download.json');

Setup View

Now we'll build a form which data we want to export into json file. For that we'll use welcome.blade.php which comes with laravel by default. So, let's see the below source code.

            <form action="{{ route('download.json') }}" method="POST">@csrf
                <div class="row">
                    <div class="col-lg-12 form-group">
                        <label for="name">Name</label>
                        <input type="text" name="name" id="name" class="form-control">
                    <div class="col-lg-12 form-group">
                        <label for="email">Email</label>
                        <input type="email" name="email" id="email" class="form-control">
                    <div class="col-lg-12 form-group">
                        <label for="phone">Phone</label>
                        <input type="text" name="phone" id="phone" class="form-control">
                    <div class="col-lg-12 form-group">
                        <label for="address">Address</label>
                        <input type="text" name="address" id="address" class="form-control">
                    <div class="col-lg-12">
                        <button type="submit" class="btn btn-primary">Submit</button>

<!-- Popper JS -->

<!-- Latest compiled JavaScript -->
<script src="[email protected]/dist/js/bootstrap.bundle.min.js"></script>


And finally, we're ready with our setup. It's time to check our output. Now go to, If everything goes well (hope so) we can see the below output.

And as all we know that our .json file structure will look like below. 

That's it for today. I hope you've enjoyed this tutorial. You can also download this tutorial from GitHub. Thanks for reading. ๐Ÿ™‚
