Convert structure to xls file

I have a structure that has 13 fields each with a table that contains a 9x5 table. How can I convert these to one excel file on different sheets?

fieldnames:

    muscles = {'Rt_Mid_Delt'   ,'Rt_Lat_Dorsi' ,'Rt_Lumbar_ES'    ...
              ,'Rt_Thoracic_ES','Rt_Lat_Gastro', 'Rt_Ext_Oblique' ...
              ,'Rt_Int_Oblique','Rt_Rect_Abdom','Rt_Glut_med'     ... 
              ,'Rt_Semiten','Rt_VMO','Rt_Rhomboid','Rt_Serratus'  };

Alyna - how are the structure and the table related? Or do you have a structure (with 13 fields) and a 9x5 table? Or is each element in the 9x5 table a structure (with 13 fields)? Can you provide an example?

Probably the easiest (but not the fastest) is to use writetable:

for fn = fieldnames(muscles)'
   writetable(muscles.(fn{1}), 'file.xlsx', 'Sheet', fn{1});
end
