This post published on the NewsPivot provides you with 11 solutions you can try when Microsoft Excel won’t open on your PC. Most of these methods come from Microsoft’s official website, and some have been proven effective. Just give each of them a try to determine your solution.

Reasons Why Excel Won’t Open

Since Excel received security updates, the problem of file not opening has become increasingly frequent. Due to the update, some file types behave differently when opened in Excel. These security patches are called KB3170008, KB3115262, and KB3115322.

For instance, Excel now opens HTML or XLA files with a .xls extension differently than before. In recent days, Excel has been warning users that opening files without Protected View security will cause a disconnection between the file and its contents. However, due to these modifications, Excel will not open some files and will instead display a blank screen for those files that are not compatible with Excel’s Protected View feature. Furthermore, Excel even won’t alert you to failure.

10+ Fixes for Excel Won’t Open Issue

Now that we know the reasons why Excel files cannot be opened, can we just accept this fact and give up using Excel to open such files? No, there are always solutions to problems. You can try the following methods to fix the issue and then try opening these files again.

Fix 1: Right Click to Open the Excel File

If nothing changes after double-clicking the target Excel file, or the Excel program starts but displays a blank white screen, you can try right-clicking the file and selecting Open. After that, you should select Workbook to resolve the issue.

Fix 2: Uncheck the Ignore Dynamic Data Exchange (DDE) Box

One of the reasons why Excel won’t start on Windows 10/11 is that it is configured to ignore other programs that use DDE. DDE aims at sending a message to Excel once you double-click on a file. Then, Excel gives the command to open the file. If Excel ignores these programs, it cannot open the file because Excel will not be able to obtain its messages.

Therefore, turning off the ignoring feature will solve the problem of Excel not opening.

  1. Create a new Excel file to open the Excel program.
  2. Go to File, Options, Advanced, and General in the new file.
  3. Untick the Ignore other applications that use Dynamic Data Exchange (DDE) option, and click OK to exit.

Fix 3: Maximize and Minimize Excel Window and Vice Versa

If the Excel software opens but displays a black screen instead of typical content, try maximizing the window (if the original window is not full screen) or minimizing the window (if the original window is full screen), which may reload the Excel page and make the hidden data to be visible.

Fix 4: Repair Microsoft Office
