It's useful in large gatherings when some individuals need to access data but not all of them need to go in and out of the page.

How to Protect Excel Sheets with Password

By creating a one-of-a-kind digital signature, you can ensure that only you have access to and control over your Excel files. Security of Excel files is an important responsibility. Starting with password protection, there are several security measures available to guarantee that your information stays private and secure. When your password secures an Excel sheet, it helps you to add a modest extra degree of security to a single spreadsheet within your workbook. 

People who have access to the Excel file may still see the spreadsheet, but they cannot make any changes unless they have the right password. You may also use a separate password for this option. So now you see it’s so easy to password protect your excel sheets and the information within when you know how to password protect excel

Third-Party Encryption To Secure Your Excel Sheets

1. 7-Zip

Using the free archive application 7-Zip to password secure numerous Excel files at the same time is a great way to encrypt many Excel files at the same time. You can use 7-Zip to encrypt an entire folder of individual Excel files, password guarding a whole group of Excel spreadsheets rather than just one at a time.

  • To begin, download and install the most recent version of 7-Zip
  • After installation, navigate to the folder containing your Excel files. 
  • Now, choose all of the files you wish to password protect by dragging your mouse cursor over them. 
  • Alternatively, hold CTRL and left click with your mouse to pick specific files. 
  • After you've made your decision, right-click and pick 7-Zip. 
  • To access the 7-Zip archive settings, click Add to Archive. On the right, you'll see encryption choices. 
  • Enter a strong and distinct password, then click OK. 

Before you open any of the Excel spreadsheets contained within the archive, you must enter a password. The spreadsheets outside the archive, on the other hand, are not password secured. Select and remove the non-password protected Excel worksheets (located outside the archive).

2. Windows Encrypting File System

The Windows Encrypting File Mechanism (EFS) is a built-in encryption system for individual files in Windows. EFS is not the same as Bitlocker, which is used for complete disc encryption. EFS, on the other hand, operates on a file-by-file basis, making it ideal for password-protecting an Excel spreadsheet.

  • To encrypt your file using EFS, right-click the Excel spreadsheet and select Properties. 
  • Select Advanced, then check the Encrypt contents to safeguard the data box. 
  • Click OK, then Apply. 

The Encryption Warning will be shown. It shows why encrypting a single file might cause problems in some situations and that encrypting the entire folder provides additional security. 

If the file is in a frequently used folder, you must unlock the folder each time you wish to view another file.

One solution is to put your text file in a different folder and use it as your secure folder. After you confirm your choice, the Encrypting File System will ask you if you wish to backup the encryption key. If you forget your decryption password, you can utilise the encryption key backup.


Using Microsoft Office's inbuilt password protection to password secure an Excel file or sheet used to be dangerous. The encryption algorithm was insufficiently strong and had several flaws, leaving it useless. Because Microsoft Office now employs AES-256, you can be confident that the password security on your Excel spreadsheet is reliable and hard to avoid with the current technology. 

Because the inbuilt password security only handles one file at a time, you may want to try using 7-Zip encryption. If you have a big number of Excel spreadsheets to safeguard, consider password protecting them all together in a single archive.
