Hello @Kovalski
There is no such a way you can do it.
You need to convert into csv as magento 2 need to import product format.
check below tutorial:-

hope it will help you
Hi,
It sure helps.
Is there a way to make databases sync on schedule. Like upload csv every morning or so?
I am suggesting extension that has autoimport functionality included. It allows to set up CSV to be uploaded regularly on time you decide to your Magento. First 14 days free for you to test and further pricing models start from $249 (one-time payment). Should be enough for start and moreover the application offers the benefits - no strict rules to import file, format can be adjusted right during upload and you set up once and just have result for multiple times imports.
Can't recommend you exact tool for that task as it's very wide task without knowing how your catalog/products structure and how they are stored at your offline business.
