Help! Excel formatting, Macros, and objects have vanished!

[andrewb90]

Hello,

I have a very strange problem that has come up in my excel file. When it was opened the other day, it was completely different! I am using Excel 2013/Windows 8, Btw.
All the shapes that I have inserted to use to assign macros are gone.
The macros within the modules are still in <acronym title="visual basic for applications" style="border-width: 0px 0px 1px; border-bottom-style: dotted; border-bottom-color: rgb(0, 0, 0); cursor: help; color: rgb(51, 51, 51); background-color: rgb(250, 250, 250);">VBA</acronym>, but my worksheet selection change code located on multiple pages has vanished.
Any images/ pictures on the worksheet are gone.
Frozen rows/columns have become unfrozen
All merged cells have become un-merged
All columns and rows have been reset to standard width/height
Color and Font have not been altered.
All hidden rows/columns have been unhidden

Really, any help would be greatly appreciated, I am borderline panicking, as I have no idea what could have caused this.

Thank you!

Andrew

Have you inadvertently saved it as a csv?
