How can PHPExcel be utilized to convert data from a database into Excel files for online editing?

To convert data from a database into Excel files for online editing using PHPExcel, you can fetch the data from the database, create a new Excel file, populate it with the fetched data, and then allow users to download and edit the Excel file online. 

// Include PHPExcel library
require 'PHPExcel/PHPExcel.php';

// Fetch data from database
// Example query to fetch data from a table
$query = "SELECT * FROM your_table";
$result = mysqli_query($connection, $query);

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

// Set active sheet
$excel->setActiveSheetIndex(0);
$sheet = $excel->getActiveSheet();

// Populate Excel file with fetched data
$row = 1;
while ($data = mysqli_fetch_assoc($result)) {
    $col = 0;
    foreach ($data as $value) {
        $sheet->setCellValueByColumnAndRow($col, $row, $value);
        $col++;
    }
    $row++;
}

// Save Excel file
$writer = PHPExcel_IOFactory::createWriter($excel, 'Excel2007');
$writer->save('output.xlsx');

// Provide download link for users to edit the Excel file online
echo '<a href="output.xlsx">Download Excel file</a>';
