Any laptop should do, as it should not require much power. You may be better off going with something that has windows as opposed to a Mac just in case something is not compatible with Apple. Nowadays though, basically everything we use can be used on either device so that should not be an issue.
As long as it can access the internet, download spreadsheets, and add extensions, then you will be totally fine. You should find something that works for you and is something that you like. As long as it isn't a very very underpowered laptop, it should work fine.
Do I need a special computer to run these extensions?
Will my Mac be okay?
Will my old windows laptop work okay?
