I have a excel sheet which contains more then 2k records. What I am doing is uploading the excel sheet and inserting the records in two table. First the record is inserted in my custom component table and after that a menu is created for each record. Now the problem what I am facing is inserting the 2K records which hangs up the browser and execution time exceeds and even cause the memory exhaust problem.
Any suggestion to do such thing without any error would be appreciable.

foreach($finalData as $key=>$val)

{

    echo $key."<br/>";

    $params     =   [

        "service_description"   =>  $val[7],

        "contact_number"        =>  $val[8],

        "contact_email"         =>  $val[9],

        "keywords"              =>  $val[10],

        "price"                 =>  $val[11],

        "banner"                =>  $defaultBanner,

        "menu-anchor_title"     =>  "",

        "menu-anchor_css"       =>  "",

        "menu_image"            =>  "",

    $custom_data    =   [

    $menu   =   JTable::getInstance('Menu','MenusTable');



    // menu if present 

    $menu->load(0);



    $menu->setLocation($custom_data['parent_id'], 'last-child');



    $menu->bind($custom_data);

    $menu->store();



    if($menu->id)

    {

        $menu->rebuildPath($menu->id);

        // store the menu id

    }
