Learn how to streamline your Excel experience by getting rid of compatibility mode with these helpful tips.
What is Excel Compatibility Mode?
Excel Compatibility Mode is a feature in Excel that allows older versions of the software to open and edit newer file formats. This mode is indicated by the words “Compatibility Mode” in the Excel title bar. While it can be helpful for collaborating with individuals using different versions of the software, it can also limit certain features and functions of Excel. Removing Compatibility Mode can be done by saving the file in the current Excel file format or by upgrading the software to the latest version. It is important to note that removing Compatibility Mode may cause formatting or feature changes in the file, so it is recommended to save a backup copy before making any changes.
Causes of Excel Stuck in Compatibility Mode
Excel may get stuck in compatibility mode due to various reasons, including opening an older version of an Excel file, using certain features that are not compatible with the current Excel version, or saving a file in a different file format. Another possible cause is when Excel detects a macro-enabled file that may contain harmful code, and it opens the file in compatibility mode as a safety measure. Additionally, using certain add-ins or plugins that are not compatible with your Excel version may also trigger compatibility mode. Knowing the causes of Excel compatibility mode issues can help you avoid them in the future and remove the mode if necessary.
How to Check if Excel is in Compatibility Mode?
Excel compatibility mode can cause issues with certain features and functions, so it’s important to know if you’re working in this mode. To check if Excel is in compatibility mode, open the “File” tab and look for the phrase “Compatibility Mode” next to the filename. If it’s there, you’re working in compatibility mode. Another way to check is to look for missing features that are normally available in newer versions of Excel. If you’re experiencing issues with certain functions or features, it could be due to compatibility mode. To remove compatibility mode, save the file in the current Excel format or convert it to the newer version. This will allow you to access all of the latest features and functions.
Sub EndCompatibilityMode()
'This code ends compatibility mode in Excel
Application.ActiveWorkbook.CheckCompatibility = False
End Sub
This code can be added to a macro in Excel, which can be run by the user to end compatibility mode. The user can then save the workbook in the current Excel format and avoid compatibility issues in the future. However, this code may not work in all scenarios, and a more comprehensive tool may be required to fix more complex compatibility issues.

To use Excel Viewer, simply download and install the software from the Microsoft website. Once installed, you can right-click on the Excel file and select “Open with” and choose Excel Viewer from the list of programs. Excel Viewer will then open the file, allowing you to view and print its contents.
While Excel Viewer does not allow you to edit the document, it is a useful tool for those who only need to view or print Excel files occasionally.
