Excel found unreadable content

I'm having issues with one of my excel files in windows explorer. Attached message, then, when I click ok, I get another message stating: "Excel found unreadable content in '1-John Doe Comm. Terr Slsprsn, No Guarantee, 2013.xlsx'. Do you want to recover the contents of this workbook? If you trust the source of this workbook, click Yes." Then, when I click yes, I get "Excel cannot complete this task with availabel resources. Choose less data or close other applications." Then after clicking this same message 6 times, I get "The workbook cannot be opened or repaired by Microsoft Excel because it is corrupt." I don't know what happened to the file, I was just in it making updates
