Why Is My Excel File Opening Blank? Excel Opening Blank is a very irritating issue usually faced by the Excel users while trying to open their Excel files. When the users double-click on an Excel file or on the workbook icon, the program starts but a blank screen appears with a white screen or in some cases grey screen instead of the projected file. In the meantime, you may be able to workaround this problem by resetting the Office apps: Open the Windows Start menu and click Settings Apps. Find Microsoft Office Desktop Apps in the app list, select it and click on Advanced options. Click Fix, wait for about one minute and then restart your device. Collaborate for free with online versions of Microsoft Word, PowerPoint, Excel, and OneNote. Save documents, spreadsheets, and presentations online, in OneDrive. The next day when I switch the PC on, a blank Word or Excel sheet (whichever I used last the day before) will open on up on my screen on startup without me touching anything. Is this not odd behaviour, or is it from a setting I need to adjust? I'm on 10 Pro October update, Office 365 on default settings.
