I doubt anyone will be able to help without a lot more details, preferably with some sample data and what you would like to produce. What do you mean by sheets?

If you must want to load all 25 sheets simultaneously then one way I can see this happen is you create 25 separate QVW files that are scheduled to run at the same time and process one sheet at a time.
