Export

[thiagoreri]

Is there a possibility, of doing the process to the contrary, make a find in the table and write in the file? In the case it would be a data export

It is possible to dump the table into a spreadsheet file using your custom finder.

$table = TableRegistry::get('SomeTable');
$manager = new Manager();

$file = new File('your/file.xlsx');
$spreadsheet = $manager->getSpreadsheet($file);
$worksheet = $spreadsheet->getActiveSheet();

$manager->write($table, $worksheet, [
    'finder' => 'myFinder',
    'finderOptions' => [], //pass options to your finder
]);
$writer = $manager->save($spreadsheet, $file);
