You could do some shadowing of your logbook in MS Excel, as it can never be a replacement for a printed booklet (a valid logbook is an official document and has to fulfill certain requirements, such as non-changeable, unique trackable etc - short, there is no electronic version for it for private flights yet. Airlines do have spent vast amounts of money to do their logbook not in the plane, but in huge data centers with very specific hard- and software - which in shear far too expensive for small planes ... I once was doing a persistent link addition to such a system and only the small feature was £ 1/2m ) If you give a **** for the requirements, you are free to do anything.
