Everyone knows that Excel is a great spreadsheet application for organizing and managing data. While it can be useful in many business applications, users also need to add password protection because the default settings don’t offer any security whatsoever. Here’s how you can make your workbook secure by adding passwords to protect your formulas from prying eyes.:
Password protecting an Excel file is a great way to keep your work safe. You can password protect the entire workbook, but still allow read-only access.
Setting a password for an Excel Workbook protects your data from being accessed by outsiders. Someone can’t access or change the file since it’s protected at the file level.
You can password-protect an Excel file so that no one else can open it. There are three methods to password secure an Excel file (I’m using Office 365 Excel in this example):
- Using the Excel Password Protection Option
- Using File Encryption in Windows
- 7-Zip is a program that allows you to compress files.
Keep in mind that there is no way to recover your password if you lose it or forget it.
1. Making Use of Excel’s Password Protection
With today’s technological advancements, this built-in security mechanism is regarded the most effective and difficult to defeat. Microsoft now employs AES-256 encryption, which enables you to secure all Microsoft Office products.
The following steps will show you how to utilize Excel’s password protection feature:
- Open Microsoft Excel and choose the document you wish to protect with a password.
- Select the Info category from the File menu.
Information about the Excel spreadsheet
- Select Encrypt with Password from the drop-down menu when you click Protect Workbook.

- After that, the program will ask for a password. Read the instructions below the pop-up window carefully and save the password in a password manager. Then press OK.
Input your password
So there you have it! The program will display a password input form whenever you need to access that Excel file.
To remove the Excel password, go to “Protect Workbook” and choose “Encrypt with password” from the dropdown menu, then erase the password from the box that opens, and then click OK.
Additional Security Option Built-In
Microsoft has also included several additional measures to secure your document from changes. To effectively secure your papers, you must also be aware of these characteristics. Other security measures are provided in the drop-down menu under the Protect Workbook option:
- Mark as Final: This option makes the Excel document final and prevents any further changes or modifications. Although this step does not provide complete protection or safeguard your information, it does effectively render the document Read-Only. The document may still be modified since this function does not need a password. To use this function, choose it and then click ‘OK’ in the pop-up window that appears.
- Protect Current Sheet: This option essentially creates a password for the currently chosen worksheet, enabling you to choose whether a portion or part of the sheet is read-only or editable. As a result, other users can only see or read information on the sheet and cannot change it. To use this function, pick the option, enter your chosen password, and choose the portions and sections of the sheet you want to lock, then click ‘OK.’
- Secure Workbook Structure: This option, like Protect Current Sheet, uses a password to protect all data and information in the Excel document. To use this function, choose it and enter a desired password before pressing ‘OK.’
- Businesses and organizational structures are the most common users of this capability. This tool enables you to choose the kind of people who are authorized to view, modify, copy, and print the document. To make this functionality active. To finish the setup, choose the choice and follow the steps.
- Add a Digital Signature: This feature gives the user confidence that the file will stay authentic throughout the transfer or sharing process. The feature enables the document to include a digital signature that is only visible to the sender and receiver. To make this functionality active. To finish the setup, choose the choice and follow the steps.
2. Using File Encryption on Windows
Another method for password-protecting Excel files is to use the Windows Encrypting File System (EFS). The EFS, or Encrypted File System, is a Windows-based integrated package for encrypting data on a file-by-file basis.
Here’s how to establish a password for Excel using Windows File Encryption:
- Select Properties from the drop-down menu when you right-click on the Excel document file.
- There’s an Advanced option at the bottom-right of the properties window. Then choose Advanced.
- Check the Encrypt contents to secure data option in the Advanced attributes box and click Ok. Then press the Apply button.
- Users who can access the Excel document may be defined by clicking Details.
Access to Users
- A warning message box will appear, advising that the folder containing the document file be secured as well, to prevent access to editing copies created by Excel each time you make a change. As a result, you must make a choice based on your preferences.
- To finish encryption, click ‘OK.’ EFS will then ask you to save a backup of the encryption key for future reference.
3. Make use of 7-Zip
7-Zip is a third-party archiver program that may be used to encrypt files and folders. This encryption application features strong AES-256 encryption in 7z and ZIP formats, as well as the ability to self-extract in 7z format.
Here’s how to password-protect an Excel file using the 7-Zip tool:
- Install the 7-Zip utility after downloading it.
- Select 7-Zip from the context menu when you right-click on the document file to encrypt.
- Select Add to archive from the drop-down option.
- Under the Add to Archive box, in the Encryption area on the bottom-right side of the window, type the desired password. Then press OK.
Window for adding to archive
Perfect! You will be asked to enter the password every time you try to access the file from now on.
Finally, we ensure that your Excel is secure and that your data is secure. It’s essential to remember that keeping records or backing up your encryption password is just as important as creating one; if not more so.
It may be as easy as writing down your passwords in a notebook, using a password manager, and storing up your encryption password. Leave a comment on how useful this tutorial was and any problems you ran across while following the steps.
