how to see the hidden columns

[yantan2006]

Good Day to all,

I have created a work sheet. it contained some data in columns. unfortunatly I left it for some time, one of my friend came and he hide some of its columns.

it contained my calculation and data. The columns are hidden form L to AN. which I can not see.

when I select column k and AO. and check hide or unhide option or freeze or unfreeze option. the unhide and unfreeze option is dried out.

he himself have forgotten the password.

is my friend has password protected these columns?
is there any way to open it?
in review tab a option is available (unprotect sheet). upon pressing it, it says enter passoword.

any suggestion what to do? how to open. any how columns could be protected with password?

Thanks a lot.
