 Converting JSON to CSV
<?php
function handle($data) {
  // Decode the JSON string into an array
  $dataArray = json_decode($data['payload'], true);
  if ($dataArray === null) {
    // JSON decoding failed
    return 'Failed to decode JSON.';
  }
  // Create an empty array to store the CSV rows
  $csvRows = [];
  // Add the CSV headers
  if (!empty($dataArray)) {
    $headers = array_keys($dataArray[0]);
    $csvRows[] = $headers;
  }
  // Add the CSV rows
  foreach ($dataArray as $row) {
    $csvRows[] = array_values($row);
  }
  // Generate the CSV string
  $csvString = '';
  foreach ($csvRows as $row) {
    $csvString .= implode(',', $row) . "\n";
  }
  // Return the CSV string or error message
  return ['payload' => !empty($csvString) ? $csvString : 'Failed to convert JSON to CSV'];
}
