Apologies for the delay in replying. I did not explored Calc so I can’t say if it is better or not. It would be nice to know the capabilities of this legendary software ! How is the online editing for Calc documents nowadays? Is there an online interface and contributive filesharing on the go?

There goes another useful tool that has been made inaccessible for most of the common users.
