In TestComplete I need to create the Excel with SmartView inbuilt features.

We have to ask the basic questions when you don't give us enough information in your post because we have no other way to find out what you have already done.

You said you have created the Excel file you need in a temp directory and you want to move it. You can use the aqFileSystem.CopyFile commands to make a copy of it in a new location.

Try that and then let us know if you still have questions.
