I am generating a Excel Export, I want to change the timestamps format in excel file from 2020-07-29 13:56:09 to just DD:MM:YYYY.
How can I change my Export Class to Format the timestamp Column in my Excel File, BTW Date is in 'E' column in Excel file.
My Export Class:

use Maatwebsite\Excel\Concerns\FromView;
use Maatwebsite\Excel\Concerns\ShouldAutoSize;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Events\AfterSheet;
class ReleaseExportView implements FromCollection, WithHeadings, ShouldAutoSize, WithEvents
{
protected $reference;
function __construct($reference)
{
$this->reference = $reference;
}
public function collection()
{
return outbound_detail::where('reference', $this->reference)->get([
'reference', 'sku_parent', 'sku_child', 'cases', 'updated_at'
]);
}
public function headings(): array
{
return [
'Reference',
'SKU Parent',
'SKU Child',
'Cases Released',
'Date Created'
];
}
// ...
/**
* #return array
*/
public function registerEvents(): array
{
return [
AfterSheet::class => function (AfterSheet $event) {
$cellRange = 'A1:W1'; // All headers
$event->sheet->getDelegate()->getStyle($cellRange)->getFont()->setSize(14);
},
];
}
}

Answer 1

On your Reference Model, add this :
public function getUpdatedAtAttribute($date)
{
return Carbon\Carbon::createFromFormat('Y-m-d H:i:s', $date)->format('d:m:Y');
}

Answer 2

You can use it's column formatting.
Try this:
// ...
use PhpOffice\PhpSpreadsheet\Shared\Date;
use PhpOffice\PhpSpreadsheet\Style\NumberFormat;
use Maatwebsite\Excel\Concerns\WithColumnFormatting;
class ReleaseExportView implements FromCollection, WithHeadings, ShouldAutoSize, WithEvents, WithColumnFormatting
{
// ...
public function map($reference): array
{
return [
$reference->reference,
$reference->sku_parent,
$reference->sku_child,
$reference->cases,
Date::dateTimeToExcel($reference->updated_at)
];
}
public function columnFormats(): array
{
return [
'E' => NumberFormat::FORMAT_DATE_DDMMYYYY
];
}
}
