Want to corrupt an Office document to prank your friends? Or is it because it has confidential information that needs to be destroyed? Well, this wikiHow will teach you how to corrupt a Microsoft Office document (or anything else) so it cannot be opened!

Using an Online File Corrupter

Go to https://corrupt-a-file.net in a web browser. Corrupt-a-File is a free tool that will corrupt any document you upload.

Click FROM YOUR COMPUTER . It's under "Select the file to corrupt." This opens your computer's file browser.

Select the Word document and click Open . The name of the file will appear under "Select the file to corrupt."

Try opening the file in Word. If you have Word on your computer, double-clicking the file should attempt to open it in that app. You'll see an error saying there's a problem with the content. Click Okay to proceed, and then Word will try (and fail) to repair or recover the content.

Using a Notepad for Windows

Select All Files from the drop-down menu. It's at the bottom-right corner of the file browser—the one set to Text Documents (*.txt) by default.

• You can use any Office document you wish—the content doesn't matter since nobody will be able to open the file.

Delete several lines of text. Seven or eight lines should be enough. However, do not delete all the text as this will prevent the file from being corrupted properly.

Community Q&A

If you are known to dislike school work, always 'forgetting' to do your homework, and you happened to turn in a corrupted document, then it is obvious you corrupted it to avoid doing schoolwork. However, if you always do your schoolwork without complaining, have no history of 'forgetting' homework, and have good grades, you might get away with it, as the only way the school can know is if you tell them, or if it is obvious as described above.

Tips

Do not use files you might need later on, as corrupted files are pretty hard to recover. Always create a dummy file or use a copy of a real document.

If you want to corrupt a file to excuse yourself from an electronically submitted school or college assignment, be very careful. Schools are becoming much more aware of this trick and some classes will give you a zero right away for turning in a corrupted document. Read your school's policies on the matter before you go ahead with this.
