CodeIgniter3.1 use the CSV batch import function to write data to the database

For example, if the website is an e-commerce shopping website, you need to perform the batch import function to operate and store all the fields in the database in the table, then, the program reads the value values in the table and inserts them into the corresponding table. Is there any similar function provided by a great God? Example
A website is an e-commerce shopping website. The batch import function is required for operating the commodities on shelves. all fields in the database are written in the table, and then the program reads the value values in the table and inserts them into the corresponding table;

Is there a similar function that a great God has done?

You can use phpexcel directly. csv is not recommended.
