public function productDataToJson(Varien_Event_Observer $observer)
{
  $array = array();
  $products = Mage::getModel('catalog/product')
      ->getCollection()
      ->addAttributeToSelect('*')
      ->addStoreFilter(Mage::app()->getStore()->getId());
  foreach ($products as $_product) {
      $array[] = $_product->getData();
  }

  $jsonData = Mage::helper('core')->jsonEncode($array);
  echo $jsonData;
  file_put_contents("c_node.json", $jsonData);
  exit;
}

I got all data from this. If this wrong, please let me know. Thank you.
