How can PHPExcel be effectively utilized to write data from a database into an Excel spreadsheet for further processing?

To write data from a database into an Excel spreadsheet using PHPExcel, you can query the database to retrieve the data, create a new PHPExcel object, iterate over the data to populate the spreadsheet, and then save the spreadsheet to a file for further processing. 

// Include PHPExcel library
require_once 'PHPExcel/Classes/PHPExcel.php';

// Create a new PHPExcel object
$objPHPExcel = new PHPExcel();

// Query the database to retrieve data
$query = "SELECT * FROM table";
$result = mysqli_query($conn, $query);

// Populate the spreadsheet with data
$row = 1;
while ($data = mysqli_fetch_array($result)) {
    $col = 'A';
    foreach ($data as $value) {
        $objPHPExcel->getActiveSheet()->setCellValue($col.$row, $value);
        $col++;
    }
    $row++;
}

// Save the spreadsheet to a file
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('output.xlsx');
