A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I've got one solution. I'm using Excel 2013. When I opened .xlsx files the main Excel grid was white (or grey). Everything else in the Excel window was visible and usable except the actual cells of the worksheet. Each cell still had it's content, it just wasn't visible. If I would change the size of the Excel window by clicking the restore button the cell contents would then appear. I solved the problem by replacing my video driver. My video card was an ATI (AMD) 5700 HD chipset. I had previously loaded the latest AMD (ATI) drivers along with all of the associated 'Catalyst' software. I completely uninstalled all of this software. Please note to do this you need to use the AMD uninstall utility that you can find in the Programs app in the Control Panel. I then restarted my computer and let Windows locate the driver for the video card. This driver, although not the latest, was probably the best, and certified by Microsoft. Once I did this, Excel worked fine. Moral of the story: Don't feel you need to get the 'latest and greatest' video drivers for your aging ATI (AMD) video chipset!
