Hi Brajamohan panda ,
You said that you deleted excel file and you cannot locate that file in the Recycle bin.
If you Delete the file by the method of SHIFT +Delete means, that file will be permanently deleted and will not be stored in the Recycle bin.
Now you need File rescue software to rescue that file. But it's also possible that you would not make any changes in that folder you deleted the file (That is you deleted the file in the desktop means, you should not create or store the files or folders in that desktop).
If you don't make any changes means ,you can rescue the file easily.
Try to find the software "Recuva" in Google search and download that file.
If you want detail i will post detail in the resource section.
