How to Make an Excel Spreadsheet “Read Only” for Others: A Guide

Making an Excel spreadsheet “read only” is a breeze. Simply navigate to the ‘File’ menu, choose ‘Info’, then ‘Protect Workbook’, and select ‘Mark as Final’. This action lets others view your spreadsheet without the ability to edit it.

After you complete this action, your Excel file will be locked for editing. Viewers can still read and copy the data, but they won’t be able to make any changes directly in the file.


Ever had the need to share your Excel masterpiece but shuddered at the thought of someone fiddling with your formulas or data? Whether you’re a meticulous accountant, a diligent student, or a passionate hobbyist, your Excel spreadsheets often contain valuable data that you may not want altered. Making an Excel spreadsheet “read only” is a simple yet effective way to protect your data from unwanted changes while still allowing others to view and analyze it.

This capability is particularly relevant to individuals or businesses who require tight control over their document’s content, or for those who want to share their work without the risk of it being tampered with. In this article, we’ll guide you through the process of locking your Excel file for editing, giving you that peace of mind.

Step by Step Tutorial to Make an Excel Spreadsheet “Read Only”

Let’s dive in and explore how to make your Excel spreadsheet viewable but not editable by others.

Step 1: Open your Excel file.

Open the Excel spreadsheet you want to make “read only”.

Opening your Excel file is the first step, just like you would do to make any other edits or review your data.

Step 2: Click on the ‘File’ tab.

Navigate to the ‘File’ menu located in the upper left corner of your Excel window.

Clicking on the ‘File’ tab will take you to the backstage view, where you can manage your file’s properties and settings.

Step 3: Select ‘Info’.

In the ‘File’ menu, choose the ‘Info’ option on the left-hand side.

Selecting ‘Info’ will bring up several options related to the management and protection of your Excel document.

Step 4: Choose ‘Protect Workbook’.

Under ‘Info’, you’ll see the option to ‘Protect Workbook’ – click on this to proceed.

‘Protect Workbook’ is where you’ll find different settings to secure your workbook, including the ‘Mark as Final’ feature.

Step 5: Click on ‘Mark as Final’.

After selecting ‘Protect Workbook’, a dropdown menu will appear. Here, click on ‘Mark as Final’.

Clicking on ‘Mark as Final’ will prompt a dialog box that informs you that the workbook will be made “read only”.

Step 6: Confirm your selection.

A message box will pop up asking you to confirm that you want to make the spreadsheet “read only”. Click ‘OK’.

After confirming, Excel will mark your workbook as final, indicating to other users that this is the intended final version of the document.


Prevents Unwanted EditsMaking your Excel spreadsheet “read only” ensures that no one can alter your data without your permission.
Data IntegrityLocking your file helps maintain data integrity, as viewers cannot accidentally modify any information.
Easy SharingYou can share your file confidently, knowing that the original content will remain intact.


Limited CollaborationOther users cannot make edits, which can limit collaborative opportunities.
Extra Steps for EditingIf changes are needed, the “read only” status must be removed, which could be inconvenient.
Potential ConfusionOther users might not understand why they cannot edit the document, leading to confusion.

Additional Information

While making your spreadsheet “read only” is a great way to protect your data, there are a few extra tips to keep in mind. Firstly, savvy users might still be able to bypass the “read only” status by making a copy of your Excel file. So, it’s not a foolproof method for protecting sensitive data. Additionally, marking a workbook as final doesn’t encrypt it or prevent it from being printed, so consider your security needs carefully.

If you need to edit a “read only” Excel file, simply go back to the ‘File’ menu, choose ‘Info’, ‘Protect Workbook’, and select ‘Mark as Final’ again to toggle the status off. This flexibility ensures that making a file “read only” is a reversible action, which can be convenient for updating spreadsheets as needed.


  1. Open your Excel file.
  2. Click on the ‘File’ tab.
  3. Select ‘Info’.
  4. Choose ‘Protect Workbook’.
  5. Click on ‘Mark as Final’.
  6. Confirm your selection.
