I have a MacBook Air on which I utilize Office for Mac 2011.

Customer Question

I have a MacBook Air on which I utilize Office for Mac 2011. Some of my saved excel files and Word files are now appearing as "blank" docs and when I try to open it says they can't be opened to check to see if they've been renamed or deleted....which they haven't been (at least not by me on purpose).........and of course I have no backup of the files. Is it possible an upgrade deleted some of these.....if so, why do the names still appear, just no content.....
JA: Just to clarify, how old is your MacBook Air and what operating system are you running?
Customer: MId 2011 OSX Yosemite 10.10.5 Office for Mac 14.7
JA: Have you installed any updates recently?
Customer: Nov 9 2016 installed security update for 10.10.5 also two itunes updates and a safari update in October
JA: What troubleshooting have you tried?
Customer: Too ignorant to know what to try......
JA: Anything else you want the Mac expert to know before I connect you?
Customer: Just that may of the excel files and word files are still there with content, only certain ones faded to "blank"

Thank you for using
My name is ***** ***** I will do my best to help.
I might have found something, please try this first:

Step 1: Change the font in the Office for Mac file

  1. Open the Excel workbook.
  2. For Excel, click the box above the first row of cells to select all cells.
  3. Select a different font.

If you can now see the text, there is a problem with the original font. Please let me know what happens, if you do see the text now I will send more instructions.
