What are the advantages and disadvantages of using Excel as an intermediary format for data extraction in PHP projects?

When extracting data in PHP projects, using Excel as an intermediary format can have advantages such as ease of use for non-technical users and compatibility with other software. However, it also has disadvantages like potential formatting issues and limited data manipulation capabilities compared to database systems. 

// Example of extracting data from Excel using PHPExcel library
require_once 'PHPExcel/Classes/PHPExcel.php';

$excelFile = 'data.xlsx';
$excelReader = PHPExcel_IOFactory::createReaderForFile($excelFile);
$excelObj = $excelReader->load($excelFile);
$worksheet = $excelObj->getSheet(0);
$lastRow = $worksheet->getHighestRow();
$data = array();

for ($row = 1; $row <= $lastRow; $row++) {
    $data[] = $worksheet->rangeToArray('A' . $row . ':D' . $row, NULL, TRUE, FALSE)[0];
}

// Process the extracted data as needed
foreach ($data as $row) {
    echo implode(', ', $row) . PHP_EOL;
}
