I was able to make a upload system and i had successfully manage to view the excel files on the browser the problem is how can i import it to Mysql.

I tried other sites but i often find them hard to understand / their code are different when executed.
And i was only allowed to use xlsx/xls files not Cvs which i find alot of guide using them.

so can anyone help me or Give me a friendly tutorial guide for importing Excel files to Mysql database
