Spreadsheet ML works on one read not another

I've recently purchased an enterprise dev subscription to Excel and cannot read in SpreadsheetML from only one of my reports. the other it works fantastic. However, the one I'm trying to get it to read in and convert over it does not. It always bombs at like 225 (no matter what) saying that the cell tag is invalid. However there are many other cell tags just like it.

Server Error in '/' Application.
