How do I password protect a workbook in Excel?

[Guest]

I used to do my personal budgets in Excel 2003 and I password protected them.
Every time I accessed the workbook I had to write the password. Now I have
the 2007 version of Excel and I don't know how to password protect my
workbooks in Excel 2007. How can I do this?

Thank you, very helpful and answered my question.

I have tried this several times and each time I get the following error:

{Microsoft Office Excel cannot access the file 'C:\Documents and
Settings\Bob\My Documents\(some random 8 character string. In this case it
was 993c7100.)' There are several possible reasons:

The file name or path does not exist.
The file is being used by another program.
The workbook you are trying to save has the same name as a currently open
workbook.}

Now, this is in the Office 2007 Student version. I did attempt to password
protect the file as an Excel 97-2003 version and had no problem protecting it
but I keep geting a nag dialog box saying that I could improve the protecting
by converting it to Excel 2007. When I do this, I get the above dialog box. I
did try using a different file name and got the same error. After several
tries, I had many of these 8 character files stored in my folder. I did
change the Sharing of the Hardrive I was saving to from Shared to unshared
but it made no difference. I also closed and then restarted Excel with the
drive unshared and same thing.

I really need the ability to protect my files. I think I should be able to
do this. It does work for 2003 .xls files but I do not want the nag dialog
box to come up each time.

Thanks for your time,

Try opening the Office Button on the top left of the Excel application.
Choose Prepare, and then Encrypt document. This forces the person to enter a
password to open and view the document.
