So one private key is for one address -in wallet you can have many addresses
every key is in row WITHOUT # and finish to date and time.
And for every wallet you have to export private keys-it is impossible to export key for two wallets together
So for me you put wrong key because is the wrong message - for label yo can put some name or whatever you want
This is helpful. Thank you. I would clarify the following (if this is wrong, somebody please correct me):
Every key is in row without # and finish to date and time and z and
for label you can put some name or whatever you want but a label does need to be present
