Can I use Calc on OS 10.13.6? Can I share data with iPad?

I have an older MacBook Pro 2011. Can I use Calc with this and can I share the spreadsheets with my iPad, iOS 13.3 or 14?

According to the system requirements LibreOffice is compatible with Mac OS 10.10 (Yosemite) or higher.

You’ll need to install Collabora Office on your IPad as Numbers doesn’t read Open Document Format files as used by LibreOffice.
