In today’s teamwork-focused workplaces, it’s vital to keep sensitive data in Excel files safe. Sometimes, you need to share reports, financial statements, or templates. You want others to see the content but not change it. Microsoft Excel has built-in features. You can password-protect a file. This lets others see it in read-only mode. This guide shows you how to do it step-by-step. It includes examples, benefits, and answers to common questions.
What is Password Protecting an Excel File?
Password protection in Excel secures your workbook with a password. This way, only authorized users can edit, view, or open the file.
There are typically three types of Excel file protection:
- Password to Open – Prevents unauthorized access entirely.
- Password to Modify – Allows anyone to open the file but restricts editing unless the correct password is entered.
- Mark as Read-Only – Users are encouraged to open the file in read-only mode unless they have a password.
This method lets users open and view files but stops editing unless they have permission. It’s great for managers, analysts, HR professionals, and business owners who want to share content carefully.
How to Password Protect an Excel File but Allow Read-Only?
Follow these simple steps to set up read-only password protection in Excel:
Step 1: Open Your Excel Workbook

Step 2: Go to “File” > “Save As”
- Click File > Save As.

Step 3: Access Tools > General Options
- In the Save As dialog box, click the “Tools” drop-down (bottom right).

This setup makes sure viewers can’t change the data, either by accident or on purpose. This keeps the file’s integrity and reliability intact.

Useful for Training & Templates
Distribute read-only Excel templates to staff or clients. They can learn or test data entry without modifying the master version.

Not directly with Excel alone. To restrict those actions, use file-level permissions or secure PDF converters.
How do I remove the password later?
Go to File > Save As > Tools > General Options and delete the password fields. Save the file again.
What if users ignore the read-only prompt?
If users click “No” when asked to open in read-only, they still need the modify password to make changes and save the file.
Is this method compatible across all Excel versions?
Yes, this works in Excel 2010 through Excel 365. However, some UI elements may vary slightly across versions.
