[AnourValar]

You can access the Phpspreadsheet directly and do whatever you want.

For example:

(new \AnourValar\Office\SheetsService())
    ->hookBefore(function (\AnourValar\Office\Drivers\PhpSpreadsheetDriver $driver, array &$data) {
        $driver->spreadsheet->createSheet()->setTitle('Foo bar'); // @see \PhpOffice\PhpSpreadsheet\Spreadsheet
    })
    ->generate('template.xlsx', [])
    ->saveAs('generated_document.xlsx');
