Importing users details from Office 365 to Active directory

Hello everyone, I have already migrated 500 users from Exchange on-premises to Office 365. then removed everything on-premises however the same 500 users are now on a new AD (DC) and I want to import all their details and info from Office 365 to Active directory on-premises including the Proxy addresses they have.

I already have exported all the users details from Office 365 so Is there any tool or way out there to import it to AD on-prem?
Note
UPN matches on both O365 and on AD.

Thanks

PowerShell? :) Either the AD module (if you are using anything above 2008 R2) or the Quest cmdlets.

How do I do the matching of users between on-premises and O365 ?

Users on O365 have all their details updated.

Users on AD have nothing except their first, last name only and UPN.

How will I update users on AD using powershell?

thanks
