Password protecting your Excel worksheet can prevent others from tampering with your data, but it’s best you never store really sensitive information in an Excel spreadsheet. Why? For the simple reason that Excel passwords can easily be cracked. This is because Excel uses a very weak form of encryption that can easily be broken use dictionary attacks and brute force attacks.

If you absolutely must use Excel to store sensitive information, then it’s always better to use the latest version of Excel, which is Excel 2013 or Excel 2010. The older the version of Excel, the easier it gets to crack the password. In versions below Excel 2010, it doesn’t even matter how complicated or long your password it, anything can be cracked.

However, later versions of Excel use more sophisticated methods of encryption and therefore the password length and complexity does matter. So it’s best to use longer passwords that are more random in nature and that include numbers and symbols.

In addition to password protecting your Excel file, you can secure it further by encrypting the entire file. This will safeguard your document if it is stolen from your computer.

Now on to actually adding a password to an Excel file. When using Microsoft Excel, there are a couple of different ways that you can password protect your spreadsheet or workbook.

One of the first and easiest methods is to password protect the entire sheet or workbook. To do this in Microsoft Excel 2007, first go to the Review tab and then click on Protect Sheet or Protect Workbook.

When a pop-up window appears, select your options and type in the desired password. Your password can be something random that no one would ever suspect (like 45pQ93S21!). In order to remember your password, use a password manager program like LastPass, which is super secure. You can also read my previous post on securing your data and passwords.

Next, password protect the entire workbook. To do this, click on File, then Save As. When the file-save window appears, type in your file name, then select the Tools drop down menu. From that menu, select General Options.

This will enable you to password protect the entire workbook and prevent anyone else from opening it and viewing its contents. At this point, you have two layers of protection: one at the sheet level and one at the workbook level.

Now, whenever you want to open that protected Excel file, you will first see a screen like the one below asking for your password.
