How to resolve error while saving?

when I try to save data from matlab command window into excel , the following error show

Warning: Added specified worksheet. 
>

In xlswrite>activate_sheet at 285

In xlswrite>ExecuteWrite at 257
  In xlswrite at 214

what does it mean?

How can I resolve it?

Noor - the above is a warning rather than an error. See https://www.mathworks.com/matlabcentral/answers/235314-please-im-having-this-messeage-displayed-when-using-xlswrite-function for some details. Also, please describe what you are saving to file (i.e. show a small code snippet) so that we can get an idea of what you have coded.
