It happens regularly that we try to open an Excel file, but it won’t open. In most cases, instead of the Excel file you want to open, you see a blank sheet of paper. Not being able to open Excel files is a common problem reported by thousands of Excel users around the world.

When you double-click on a file to open it, it opens, but you see a blank or gray screen instead of the file’s contents. In this case, you just know that the Excel file cannot be opened. You need to know what to do if the Excel file cannot open. In this article, we will look at what you need to do if your Excel files won’t open.

What causes an Excel file not to open?

Excel won’t open a file because it is damaged. This happens, for example, when Excel hangs when saving a file or when a problematic macro fails to save the file properly. In this case, the file is often so corrupted that you can no longer open it with Excel by double-clicking on the file in file explorer.
