xlswrite Issue: not writing an entire column

I have this dataset that I have done all sorts of analysis on and I've compiled it into this matrix and want to write it to an excel file. Thought that would be easy.

I just used the following:

xlswrite('Data.xlsx',data)

But when I open the new excel file, the entire first column is blank. The 'LEK_01' (or other subject ID) is just not there. Any idea why that is? I checked format of all the entries in the cells and they are all in agreement. I'm not getting any errors either.

Thanks in advance!

Example of first few rows of "data"?

The first column of data is a column of cells each containing a cell containing...

xlswrite can't handle that.

  data(:,1)=data{:,1};         % recast the cells to the cellstrings
  xlswrite('Data.xlsx',data)   % will work now
