When working on Microsoft Excel issues, I commonly come across an the issue of Microsoft Excel sheets opening to a blank grey screen.
The most common time I see this error is when Office 2007 or Office 2010 was removed and Microsoft 2016 was installed.
If the above statement is true, than more than likely this quick fix should work for you.
Step One: Close all Microsoft Office programs
Step Two: Go to Control Panel > Programs > Uninstall a Program
Step Three: Find Microsoft Office 365 Program and Right-Click and select Change
Select Quick Repair
Once the Office Quick Repair is complete, try opening an Excel document from File Explorer. It should open correctly now.
My guess would be that it is a file association issue or something from the old Excel version that causes the issue.
Let me know if that worked by sounding off in the comment section. This was posted by techspeeder.
