Hey I would like to know how this works, How Excel file can be open with these generated usable password, what is the logic behinds this scenario.

AABBAABBBAAW equals to 12345 in what sense ?

Cracked password Lock password
One usable password is AABBAABBBAAW 12345
One usable password is AAAABAABAAAx allthebest
