Create cases from excel sent via email?

I saw https://www.youtube.com/watch?v=CpHalKWagsY video.
but not enough detail? 

how to program the same behavior? but without installing external packages? 

what I need is exactly the same
send excel to some address that will automatically generate cades and send emiail notifications

I think this seems challenging as not posssible to read Excel in Apex.
Excel files(xls,xlsx etc) are not a text based file. They are binary files. Thus unlike CSV(text based) they cant be read line by line/character by character.

Chek this for reference:

Thanks!
