Jeanne,
I imagine you do not have enough data to worry about this too much.
If you have into hundreds of megabytes of raw data, then the tune might change.
Stay with mainstream spreadsheets and you will be OK - Excel, Google tools, Microsoft free on-line tools, etc.
Whatever is free/cheap/already paid-for is plenty fine.
These are all capable of producing compatible data sets that easily can be moved back and forth, system to system.
Let someone else test the so-called "latest and greatest".
The "wave of the future" will be decided by Microsoft/Amazon/Google corporate offices anyways.
Don't bother guessing their minds.
Check back in 5 years and regroup.
PS: I do administer databases for living, so...
