The FBR portal is not bad (considering the overall deteriorating situation of almost everything in Pakistan). The portal allows you to export/ import your data for offline filing via MS Excel; except for one minor problem: several sections of the sheet are protected by a password! Yes, you read it correct. I repeat: the Excel sheets which you have to fill for your Income Tax returns are password protected!
A few weeks ago, there was a letter to the editor on precisely the same topic in Dawn.
If you are using Excel 2007, the menu option to "unprotect" or unlock your sheet is Review -> Changes -> Unprotect Sheet. It will ask you for a password but FBR's website gives you no clue as to what the password is. Fortunately for us, cracking Excel passwords is not hard. There can be many password which can unlock one sheet. In the case of FBR's eFiling Excel sheets, one such password is AABABBABABBW.
A macro to crack Excel passwords in general is provided below (author unknown):
