In theory you should not be able to do that.
There are some exceptions. If you are in a corporate network and have things setup correctly in advance, there is a tool that administrators can use

Microsoft Office 2013 crackable, so look to Office password recovery

What's the big deal, you say? Well, Microsoft Office 2013 has a revamped
password-protection scheme presumably employing stronger hashes and encryption keys. But Elcomsoft has found flaws in the implementation that allows its Advanced Office Password Recovery and Elcomsoft Distributed Password Recovery tools to "crack" these passwords
instantly (for write-protected files) or via brute force in a relatively short period of time (for opening-protected files).
No Office 2013-generated file is immune. Passwords in business applications such as Access, Excel, PowerPoint, Project and Word are all fair game.
