Excel Encryption: How to Password Protect Excel Files?
Nowadays, for modern people, the Excel has become an indispensable tool for their work because of its convenience and usefulness. Of course, not only that, in daily life, people need to use Excel files to record both life and business matters, such as daily expenses, passwords for various accounts especially bank account and plans to be completed during a certain period of time. In your Excel files, there are not only some important data of work but also the privacy of your personal life. So, you have to prevent these significant files from leaking out. In this case, encrypting Excel files is particularly important!
In fact, Excel itself also provides you with a basic file protecting service, and that is to grant read-only access to the worksheet so as to prevent it from malicious tampering or accidental deletion. However, these primary file protection features of Excel stated above may not be able to meet your needs. So, next we will provide you with several ways to encrypt Excel files with password, including using Excel’s built-in password protecting function, and using an encryption software to lock Excel files.
Method 1. How to Password Protect an Excel File with Excel’s Built-In function?
Warning: Microsoft cannot restore forgotten passwords, so make sure that your password is not easy to forget! Additionally, there are no restrictions on the passwords you use for Excel encryption with regards to length, characters or numbers, but passwords are case-sensitive.
The specific steps for Excel encryption are as follows:
- In 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 should be something random that no one would ever suspect.
- Next, 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. At this point, you have two layers of Excel encryption with password: one at the sheet level and one at the workbook level.
Now, whenever you want to open that encrypted Excel file, you will first see a screen like the one below asking for your password.
