Hello, Dilip,
could you set logging on the stage where you write collection to excel and in the log you should see the values which should be written. How about calling Show action from MS Excel VBO - does it launch excel instance? Are you sure you are creating the same excel or opening the right excel? Can you take screen shot of your process and action where you write it? Without any information from log it is quite difficult to find the root cause.
Regards,
