Load data into multiple excel sheets depending on conditions dynamically

Hi 
I am working as ETL developer i have a situation please help me out. I have to create multiple sheet in one excel file with different queries. Like i have to check if the particular column is null then the record against this query should be in excel file and i have to check another column with other name if it is null or empty and then create a sheet for it and sheet should be created only if the query returns some result otherwise there should not be any empty sheet.  i have 8 different columns to check .
