I have installed a great dark theme for Windows 7 however the disadvantage is that in Microsoft Excel 2016 all cells have a default dark background now.
Microsoft Word had the same problem but changing background for Normal.dotm (in the AppData -> Templates) and having selected "Show background colors and images in Print Layout" - have fixed this problem.
However I can't fix it for Excel. I have tried to do templates and theme and save a template in XLSTART folder in AppData (everything possible i could find online) - but nothing really worked, you cant just open excel and start working. With template it opens first worksheet with white background and if you want to insert another worksheet - its again dark.
Is there a way to change default background color of cells? So that even if i open an excising documents - it will have a white background?
