Magento 2 : Create Review & Rating programmatically from other db or csv?

This code is for import reviews from the other database table into magento2 product review.
Step1- Please empty review and rating tables.

Magento 2 Database table list.

1. review
2. review_detail
3. review_entity_summary
4. review_store
5. rating_option_vote
6. rating_option_vote_aggregated

Step2- Create 2 tables in your magento database test_customer and test_reviews.
CREATE TABLE `test_customer` (
  `customerid` int(11) NOT NULL,
  `firstname` varchar(255) NOT NULL,
  `lastname` varchar(255) NOT NULL,
  `emailaddress` varchar(255) NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;



CREATE TABLE `test_reviews` (
  `id` int(11) NOT NULL,
  `lastmodified` varchar(255) NOT NULL,
  `productcode` varchar(255) NOT NULL,
  `reviewtitle` varchar(255) NOT NULL,
  `rate` varchar(255) NOT NULL,
  `customerid` varchar(255) NOT NULL,
  `name` varchar(255) NOT NULL,
  `location` varchar(255) NOT NULL,
  `active` varchar(255) NOT NULL,
  `reviewdescription` text NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;



Here you can insert the data from your csv's or other database

Step3- create a php page and paste the below code.

<?php
error_reporting(E_ALL);
set_time_limit(0);
ini_set('display_errors', '1');
ini_set('max_execution_time', 0);
ini_set('memory_limit', '3072M');
ini_set('auto_detect_line_endings', TRUE);

Magento 2 : issues with M2E Pro 'Duplicated line on invoice/order for configurable product'[solved]

Duplicated line on invoice/order for configurable product

When configurable product is ordered, Magento show 2 lines in order (and in invoice)
configurable product generates 2 lines : one with the actual price and the other one with $0 price.

Go this location:
app/code/Ess/M2ePro/Plugin/Order/Magento/Quote/Model/Quote/Item/

Replace 2 function :

public function aroundConvert($interceptor, \Closure $callback, $item)
    {
        return $this->execute('convert', $interceptor, $callback, [$item]);
    }

    // ---------------------------------------

    protected function processConvert($interceptor, \Closure $callback, $arguments)
    {
        $orderItem = $callback($arguments[0]);

        $this->eventManager->dispatch(
            'ess_sales_convert_quote_item_to_order_item',
            [
                'order_item' => $orderItem,
                'item' => $arguments[0],
            ]
        );

        return $orderItem;
    }
 

    To:
 
 
   public function aroundConvert($interceptor, \Closure $callback, ...$arguments)
    {
        return $this->execute('convert', $interceptor, $callback, $arguments);
    }

    // ---------------------------------------

    protected function processConvert($interceptor, \Closure $callback, $arguments)
    {
        $orderItem = $callback(...$arguments);

        $this->eventManager->dispatch(
            'ess_sales_convert_quote_item_to_order_item',
            [
                'order_item' => $orderItem,
                'item' => $arguments[0],
            ]
        );

        return $orderItem;
    }
