You need to include your query execution in your loop. Not after it:

foreach($sheetData as $row){
    if($flag==0 || $row['E']== 'Not Found on build.com'){
        $flag =1;
        continue;
    }
    $product_id =$row['A'];
    $ext_product_id=$row['D'];

    $sql = "UPDATE 13_product_id SET ext_product_id='$ext_product_id[$row]' WHERE product_id='$product_id[$row]'";
    mysqli_query($con,$sql) or exit(mysqli_errno()); 
 }
