How to properly use composer packages in wordpress?

I need to implement in a wordpress instance a feature that allows me to search for the most recent file with extension .xlsx in the wp-content/upload directory, once the file has been identified, it should be interpreted and finally insert the excel data in the wp_posts and wp_postmeta tables Following a certain logic.

The packages of interest are

  • symfony/finder
  • phpoffice/phpspreadsheet

What is the correct way to integrate and use packages within wordpress?

I am new to worpress and I do not know how in the structure and philosophy of wordpress to do this. Thanks for the time.
