Import/Export Functionality

[yashpatel1998]

Is your feature request related to a problem? Please describe.
One problem that I see with the current application is that if we are to change devices then the data will not be transferred. Hence, it will be beneficial for end users if they can export the data to a file and then import it back

Describe the solution you'd like
Considering the privacy aspect I will like to have an Import/Export(to and from CSV/Excel) feature instead of syncing with cloud.

Describe alternatives you've considered
One other alternative I can think of cross app sync functionality. Similar to how the Brave browser has implemented, but using either hotspot or bluetooth of the device.

Additional context
I will like to contribute to this project by building the CSV solution, if that is okay.

Thanks
