strange output when using writetable function

t=table(x,y,ID)
%x,y are vectors, ID is cell array
writetable(t,'Data.xlsx');

I am getting for ID an output which ID_1,ID_2,....ID_6 where each column is having a letter

for example:

699964 appears fully under ID_1

on the other hand,68508C appears

6 8 5 0 8 C

where each digit or letter appears under a different column

Any help is appreciated

Does your ID cell array have some empty cells?

No

Wesso, you are going to have to give a short example of exactly what's in the table. Impossible to guess what's going on otherwise. When I do this for example

t = table([1;2;3],{1; 1:2; 'abc'})
writetable(t,'test.xlsx')

in R2015b, I don't get what you seem to be describing.
