Sometimes you want users to see your spreadsheet but not make changes. Here’s where Excel’s read-only password feature comes in handy.
Enable Read-Only Mode for Limited Access
Under File > Save As > Tools > General Options, you can add two types of passwords:
- Password to open (for full access)
- Password to modify (for editing only)
Choose to apply just the second option, and voila—you’ve password protected your Excel file but allowed read-only access.

- In SharePoint, restrict permissions at the folder or document library level, limiting who can open or edit the file.
These options are especially helpful for teams handling confidential data through Microsoft 365’s cloud environment.
How to Remove Password Protection from an Excel File

Frequently Asked Questions
Q1: What is the difference between “Protect Workbook” and “Encrypt with Password”?
“Encrypt with Password” (found under File > Info) prevents anyone from even opening the file without the correct code. “Protect Workbook,” located under the Review tab, is different. It typically means protecting the file’s structure. This stops users from adding, deleting, or renaming worksheets.
Q2: Can I recover a forgotten Excel password?
Unfortunately, no. Microsoft does not have a “Forgot Password” feature for encrypted Excel files for security reasons. If you lose the password, the data is essentially unrecoverable. It is highly recommended to store your passwords in a secure password manager like 1Password or Bitwarden.
Q3: How do I protect only certain cells while letting users edit others?
To do this, you must first select the cells you want to stay “unlocked,” right-click them, go to Format Cells > Protection, and uncheck Locked. Then, go to the Review tab and click Protect Sheet. Now, only the cells you explicitly unlocked will be editable.
Q4: Does password protection carry over to Excel Online or SharePoint?
If you password-protect a file using the Excel Desktop app and then upload it to SharePoint or OneDrive, the password remains active. You can’t add a new password to a file in the Excel Web version. To apply encryption, you need to use the desktop application.
Q5: Is it possible to set a “Read-Only” password?
Yes. Through the Save As > Tools > General Options menu, you can set a “Password to Modify.” Anyone can open and read the file. However, they can’t save changes to the original document without the secondary password.
