Free Excel alternative for Mac OS? I need free alternative of Excel in Mac Os. I know that there is Open Office, but I am not sure if it is even supported anymore.

Any ideas?
By adding a table to Numbers, you can use Apple's replacement instead of a third party's. Numbers is free for anyone with an App Store account (which may require registration and a payment card - but no charge whatsoever).

Numbers is supported and designed to replace Excel for the majority of Mac users.
