A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I had a similar problem. I opened a workbook which I have been working for years. Only that, for the last few updates I had not backed it up in my External HD. It happened, today when I opened my workbook it opened totally in white. No grids, nothing. However, when I opened up the Ribbon and got to the "View" tab, I saw something strange, Everything was static except the "Unhide". When I clicked it, everything in the page returned to its rightful place. Apparently, I had accidentally hidden the whole page.
I place this experience here in case someone is going through the same experience. Before doing anything else, get up to your Ribbon and check your "View" Then follow up and repeat what I did.
This might be and old problem, but someone might be having a 2016 recurrence.
