## README


## Quick start

Install via composer:

```
composer require Pudding/fast-excel
```

Export a Model to `.xlsx` file:

```php
use Pudding\FastExcel\FastExcel;
use App\User;

// Load users
$users = User::all();

// Export all users
(new FastExcel($users))->export('file.xlsx');
```

## Export

Export a Model or a **Collection**:

```php
$list = collect([
    [ 'id' => 1, 'name' => 'Jane' ],
    [ 'id' => 2, 'name' => 'John' ],
]);

(new FastExcel($list))->export('file.xlsx');
```

Export `xlsx`, `ods` and `csv`:

```php
$invoices = App\Invoice::orderBy('created_at', 'DESC')->get();
(new FastExcel($invoices))->export('invoices.csv');
```

Export only some attributes specifying columns names:

```php
(new FastExcel(User::all()))->export('users.csv', function ($user) {
    return [
        'Email' => $user->email,
        'First Name' => $user->firstname,
        'Last Name' => strtoupper($user->lastname),
    ];
});
```

Download (from a controller method):

```php
return (new FastExcel(User::all()))->download('file.xlsx');
```

## Import

`import` returns a Collection:

```php
$collection = (new FastExcel)->import('file.xlsx');
```

Import a `csv` with specific delimiter, enclosure characters and "gbk" encoding:

```php
$collection = (new FastExcel)->configureCsv(';', '#', '\n', 'gbk')->import('file.csv');
```

Import and insert to database:

```php
$users = (new FastExcel)->import('file.xlsx', function ($line) {
    return User::create([
        'name' => $line['Name'],
        'email' => $line['Email']
    ]);
});
```

## Facades

You may use FastExcel with the optional Facade. Add the following line to ``config/app.php`` under the ``aliases`` key.

````php
'FastExcel' => Pudding\FastExcel\Facades\FastExcel::class,
````

Using the Facade, you will not have access to the constructor. You may set your export data using the ``data`` method.

````php
$list = collect([
    [ 'id' => 1, 'name' => 'Jane' ],
    [ 'id' => 2, 'name' => 'John' ],
]);

FastExcel::data($list)->export('file.xlsx');
````

## Global helper

FastExcel provides a convenient global helper to quickly instantiate the FastExcel class anywhere in a Laravel application.

```php
$collection = fastexcel()->import('file.xlsx');
fastexcel($collection)->export('file.xlsx');
```

## Advanced usage

### Export multiple sheets

Export multiple sheets by creating a `SheetCollection`:

```php
$sheets = new SheetCollection([
    User::all(),
    Project::all()
]);
(new FastExcel($sheets))->export('file.xlsx');
```

Use index to specify sheet name:
```php
$sheets = new SheetCollection([
    'Users' => User::all(),
    'Second sheet' => Project::all()
]);
```

### Import multiple sheets

Import multiple sheets by using `importSheets`:

```php
$sheets = (new FastExcel)->importSheets('file.xlsx');
```

You can also import a specific sheet by its number:

```php
$users = (new FastExcel)->sheet(3)->import('file.xlsx');
```

### Export large collections with chunk

Export rows one by one to avoid `memory_limit` issues [using `yield`](https://www.php.net/manual/en/language.generators.syntax.php):

```php
function usersGenerator() {
    foreach (User::cursor() as $user) {
        yield $user;
    }
}

// Export consumes only a few MB, even with 10M+ rows.
(new FastExcel(usersGenerator()))->export('test.xlsx');
```

### Add header and rows style

Add header and rows style with `headerStyle` and `rowsStyle` methods.

```php
$header_style = (new StyleBuilder())->setFontBold()->build();

$rows_style = (new StyleBuilder())
    ->setFontSize(15)
    ->setShouldWrapText()
    ->setBackgroundColor("EDEDED")
    ->build();

return (new FastExcel($list))
    ->headerStyle($header_style)
    ->rowsStyle($rows_style)
    ->download('file.xlsx');
```
