problem with xlswrite while obeying excel limits

I know that there are a lot of posts on this subject but I have searched them extensively and still can't figure out why I am getting this error.

[statusD,msginfoD] = xlswrite([NewName '.xls'],DataForExport,2);

the variable DataForExport is a cell array that contains 60001 rows and 12 columns, every cell contains ether a numeric value or a string and none of the strings are longer than the limited 991 charaters (actually the longest is 50). Yet I still get the error;

   message: 'Error: Object returned error code: 0x800A03EC'
    identifier: 'MATLAB:COM:E2148140012'

I don't get the error if I write only the first 6 columns of data but the second 6 columns of data can not be written serially and the error is thrown again.

Any Ideas?

What is the maximum length of the sum of the first 6 columns of the data?

I had the following error:

       message: ''
    identifier: 'MATLAB:COM:E2148140012'

and it boiled down to having a column with incorrect excel formulas in my cell array, like:

 '=HYPERLINK("file:///myfolder/"& filename &".pdf")'

where it should have been

 '=HYPERLINK("file:///myfolder/filename.pdf")'

The erroneous formula generates an "Invalid Name Error" if pasted to excel.
