How To Create A Read-Only File In Excel And How To Remove It Too!

Written by co-founder Kasper Langmann, Microsoft Office Specialist.

Sometimes we may have an Excel workbook that would be sensitive to changes.

For instance, Jake, who reached out to us and asked:

I have an Excel file with some important functions. How can I share this file with my clients without allowing them to make changes to it?

In this case, it will be necessary to protect the workbook from any changes intentional or otherwise by other users that have access to it.

We may still want to allow a user to make changes and save those with a new filename or to a different location.

A great way to ensure the integrity of such a workbook file would be to enable the ‘read-only recommendation’.

How to create a ‘READ-ONLY’ file

Let’s say we maintain a monthly report that we make changes to as new data becomes available.

We now need to share the updated report to users that need the new data and metrics.

However, we want to make sure that any changes made by other users do not get saved to the original file. Instead, these users will be forced to rename the file – or to save it to a different location.

We can do this by making sure other users can choose the option of ‘read-only’ mode to decrease (but not eliminate) risk of the file being changed.

The first step in how to make a file ‘read only’ is to enable the setting

1: Go to the ‘File’ tab and select ‘Save As’.

2: Select ‘Browse’


3: Click on the ‘Tools’ dropdown at the bottom of the ‘Save As’ dialog box.

4: Select ‘General Options’ from the list.

5: Make sure the ‘Read-only recommended’ box is checked in the ‘General Options’ dialog box and click ‘OK’

6: Select ‘Save’.

It’s that simple.

Now every time the file is opened, the user will be prompted to ‘Open as read-only?’.

Note: This method allows the choice of ‘Yes’, ‘No’, or ‘Cancel’

If the user clicks ‘Yes’ to the question to open as ‘read-only’, no changes to the original file (name) can be made.

This doesn’t quite mean that we cannot make changes to the open file.

For anyone wondering how to change a ‘read-only’ file, there actually is a bit of a workaround.

Note in the next figure that if we try to save a ‘read-only’ file that it prompts us to change the file name or location.

So that’s how to change a ‘read-only’ file!

We simply rename the ‘Save As’ filename or save it to a different file location.

It’s a pretty simple procedure to save a workbook as ‘read-only’ and it adds some extra control over the workbook.

But it’s really not protecting it from changes since each user that opens the workbook has the option not to open in ‘read-only’.

It’s more of a reminder to anybody who might forget that “hey, don’t mess this copy up!”.

Now that we have covered the steps to make a workbook file ‘read-only’ let’s look at how we remove the ‘read-only’ option…

How to remove ‘read-only’

Let’s now turn to the task of how to remove ‘read-only’ recommendations from the file.

For instance, say it’s to add new data and make some calculations. This updates the metrics for the stakeholders that use the report.

We need to have a way to remove ‘read-only’ from our file in order to easily save the changes to the current filename.

Kasper Langmann, Co-founder of Spreadsheeto

One thing to note is that our workbook must not be open in ‘read-only’ mode for us to be able to actually save our changes after we remove ‘read-only’.


When we open a ‘read-only recommended’ file that it prompts us for a ‘Yes’ or a ‘No’ to the question of whether we would like to open as ‘read-only’ or not.

We need to click ‘No’ in order to be able to save our changes.

1: When opening the file, select ‘No’ when prompted.

2: Click on ‘File’, then ‘Save As’ and then click on ‘Browse’.


3: Click on ‘Tools’ at the bottom of the ‘Save As’ dialog box and select ‘General Options’.

4: Once the ‘General Options’ dialog box appears, uncheck the box next to ‘Read-only recommended’.

5: Then click ‘OK’ and the workbook is no longer in ‘read-only’ mode.

There are a couple of things to note about workbooks that are opened as ‘read-only’…

Kasper Langmann, Co-founder of Spreadsheeto

First, if we open a file in ‘read-only’ there is an indication at the top of the file in the filename that the workbook is, in fact, ‘read-only’.

Another thing to note is what will happen if we try and save changes to the same file that is in ‘read-only’ mode.

Cannot save as that name

As you saw earlier, the only way to save changes to a ‘read-only’ file is by renaming it or saving it to a different location.


So, there it is. The basic steps to both enabling and disabling ‘read-only’ mode in Excel 2016.

It’s a simple technique that can provide more control over the integrity of files without going to the extremes of things like password protection.

Furthermore, it still allows other users to make changes but ensures they can only do so by renaming the file or saving it to a different location than the original file.
