Export nested cell array to excel

I have a nested cell array where each cell has three columns but different number of rows. I need to export the values to excel keeping the columns intact but using writecell gives me an error 'Nested cell arrays are not supported'. How can I export the values to excel?

Here's a quick example:

A1 = {1,1,1};
A2 = {2,2,2;2,2,2};
A3 = {3,3,3;3,3,3;3,3,3;};
A = {A1, A2, A3}; 

writecell(A, 'mydata.xlsx');

Error using writecell
Nested cell arrays are not supported.

You could just try to avoid using the cells, and just create one big matrix (array) with NaNs and then fill in your data. However, this would be an easy workaround just in case you have just these few columns and numbers. If you have much more numbers and columns, it could be bit trickier.

See my example:

m = NaN([3 6])

m = 3×6

NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN

m(1:3,1) = [1 1 1]

m = 3×6

1 NaN NaN NaN NaN NaN 1 NaN NaN NaN NaN NaN 1 NaN NaN NaN NaN NaN

... and go on.

Hope I helped.
