Excel document to MySql database with specific selection and parameters?

Question

PHP

Is it possible to do something so that the admin could upload an excel file to the site, it was automatically processed and different columns / lines of the document were sent to different users depending on the name of the first line, for example?
Is it better that they go to the database?
Can certain rows/columns be sent to different databases?
Is it possible to work with excel files or is it better with CSV?
I have never dealt with excel processing because there are so many questions

Answer 1

xls2csv, then LOAD DATA INFILE to MySQL, and then do whatever you want with them.
