And it could be a nightmare if, at that point in time, Microsoft Excel decides not to open (arghhhhh!). Unfortunately, this unexpected behavior is quite common where Excel refuses to open one of your important Excel files, or fails to open the Excel application altogether. So, if you are suffering from the ‘Microsoft-Excel-won’t-open’ syndrome, this article is just what you need. In this tutorial, I will cover the reasons why Excel refuses to open and the possible solutions that can help you in this situation. So let’s get started!
Possible Reasons Why Microsoft Excel Won’t Open
Since Excel is a tool that has to work seamlessly with other applications and operating systems, there are many things that can go wrong with it. And of course, there is always a possibility that the Excel application in itself is the problem. Below are some possible reasons due to which Microsoft Excel won’t open on your system:
How to Fix Excel Files Not Opening
Now, let’s have a look at some of the methods that you can use to fix the issue of Excel files not opening. I’m listing these fixes in an order in which these are most likely to work.
Uncheck the Ignore DDE box
The most common and easiest fix is to make sure that the correct setting is enabled for the Dynamic Data Exchange (DDE). DDE is how Excel interacts with other applications. By default, the DDE setting is disabled, but in case it gets enabled by any chance, then it could lead to your Excel files not opening on your system. When this happens, you will be able to open your Excel application from the start menu, but you won’t be able to open individual Excel files. Below are the steps to fix this DDE issue: If this setting was enabled earlier and you have disabled it using the above steps, this was most likely the issue and it should get sorted now. In case this method doesn’t work, keep reading!
Turn OFF Add-ins
A lot of people use third-party add-ins in Excel that allow them to enhance the functionality and be able to use many features that are not there in Excel by default. One of the add-ins that I used to use in my full-time day job days was ‘ThinkCell’, which allowed us to create beautiful charts that were not possible with Excel itself. And sometimes these add-ins end up being the problem where you not able to open your Excel files. It has an easy fix – disabling the add-in. Below the steps that you can use to disable an add-in in Excel: Now try and open an Excel file that wasn’t opening earlier. If the item was the issue, the file should open now. Many a time, it’s a one-off issue and the add-in will work perfectly even if you enable it now. In case you enable the add-in and you still face the same problem, you can be sure that the add-in is corrupt I need to be permanently disabled.
Repair Microsoft Office
Another possible reason that causes Excel files to not open could be that your Microsoft Office application is corrupt and need to be repaired or reinstalled. But since reinstalling is a little more work, let’s try the repair option first. Follow the steps below to repair the Microsoft Office application on your system: Follow through with the steps that show up and within a few minutes, it will repair your Microsoft Office application. If a corrupt Microsoft Office application was the issue, it should be fixed with the above steps. But in case you’re still not able to open Excel files, let’s try more fixes.
Reset Excel File Associations
File Association is what makes sure that when you open an Excel file, it uses the Excel application to open that file. And sometimes, these file associations go wrong and when you click on an Excel file, it would not know that it needs to use the Excel application to open it. The fix – resetting file associations Below are the steps on how you can do this: If a mismatched file association was the issue that was not letting your Excel files open, this would fix it. Note that since we have reset the default for all the applications on your system, in case you had manually made any changes and specified any specific file extension to be opened with a specific application, that would also be set to the default. If you don’t want to reset the default for all the applications and only for the Excel files, click on the ‘choose default applications by file type’ option. In the screen that shows up, locate the Excel files extensions (.xls, .xlsx, .xlsb, .csv, etc.) and set XLS the default application for these.
Disable Hardware Graphics Acceleration
Hardware graphic acceleration is something that helps your system perform better, especially when using Microsoft Office applications such as MS Excel or MS Word. But many times, this may also lead to your Excel files not opening or your system or files crashing. So, if everything else fails, it’s worth trying this method. Hardware graphic acceleration is enabled by default and disabling it can solve the issue. Here is how you can do it: If hardware graphic acceleration was the issue, your Excel files should start opening now.
When Everything Fails – Reach out to the Microsoft Support
And finally, there is only so much troubleshooting you can do. If nothing else has worked for you so far, it’s best to reach out to Microsoft support and see if those guys can help you. Many times, these issues could also arise from some recent update that Microsoft released which may have inadvertently caused this issue.

So these are the methods that you can use to troubleshoot when your Microsoft files won’t open. In most cases, it should be sorted by simple setting changes such as disabling third-party add-ins or resetting file associations, and in some rare cases if you’re not able to identify the issue the best thing is to reach out to Microsoft support.
