Hello,
I have brought an idea which you people might already know, the topic under discussion here is “How to protect word documents and excel spreadsheets with one’s own password?” 
I came to know about this when I was just saving the document I had made. This option might be useful for the people who work on important files of office. This is also helpful if a child operates a computer in which important files are kept. Confidential files can also be kept safe through this option.
So all you have to do for this is while saving the file, Go to the option “save as”. You will get a dialog box something like this:
 
By clicking this dropdown box shown above you will get a list in which you have to select “General Options” and type the required password.
The next time you open this document you will be asked for the password.
This can also be done for documents (Word), spreadsheets (Excel), presentations (PowerPoint).
