How to create guest order programmatically for Guest User

Question

I have followed Create order programmatically in Magento 2

But it is saving the customer.

And When I skip customer set data and customer save then It's getting an error report like

"Please enter customer email".

Any thoughts ??

The above answer is correct but the standard way is not to create the Customer in case of Guest Checkout.

            $cartId = $this->cartManagementInterface->createEmptyCart();

            /** @var \Magento\Quote\Model\Quote $quote */
            $quote = $this->cartRepositoryInterface->get($cartId);

            $guest = true;
            if ($guest) {
                // Set Customer Data on Qoute, Do not create customer.
                $quote->setCustomerFirstname("Guest First Name");
                $quote->setCustomerLastname("Guest Last Name");
                $quote->setCustomerEmail("guest@123.com");
                $quote->setCustomerIsGuest(true);
            } else {
                // Create customer object and assign to qoute 
                /** @var \Magento\Customer\Api\Data\CustomerInterface $customer */
                $quote->assignCustomer($customer);
            }

Also, the best place to check the sample code for anything to do programmatically is in Magento Integration test cases present in dev/tests/integration/testsuite/.

You can check below blog for create order programmatically, I have given full demo for create order in Magento 2, Check link, Create Order Programmatically

You need to skip Customer create step, In above blog, YOu need to replace,

if(!$customer->getId()){
            //For guest customer create new cusotmer
            $customer->setWebsiteId($websiteId)
                    ->setStore($store)
                    ->setFirstname($orderInfo['address']['firstname'])
                    ->setLastname($orderInfo['address']['lastname'])
                    ->setEmail($orderInfo['email'])
                    ->setPassword($orderInfo['email']);
            $customer->save();
        }

with,

if(!$customer->getId()){
    //For guest customer create new cusotmer
    $customer->setWebsiteId($websiteId)
            ->setStore($store)
            ->setFirstname($orderInfo['address']['firstname'])
            ->setLastname($orderInfo['address']['lastname'])
            ->setEmail($orderInfo['email'])
            ->setCustomerIsGuest(1);
}
