dear sirs

i have a peculiar problem and i do not know this is the forum to whom
i should address.

i have created a very important spreadsheet in excel using my brother's
laptop. when i tried to save the file in my flashdrive, it asked for a password.
i save the file giving a password which i just forgot.

when i tried to open the file in my laptop, i could not open the file since
it is protected by sysmatic endpoint encryption and i need to give the
correct password to open the file.

how can i open the file without password.

kindly help me.
