Ideally, the macro would run in Windows and would initiate the opening of a specific spreadsheet at a certain time. From there it would run a specific macro within the spreadsheet. One completed, it would be saved and closed. Two possible types of spreadsheets would be involved.

1. Specific time to be opened each day - run macro with spreadheet. Then close.
2. Always open, but running in intervals with intervals to determined by myself in minutes and seconds.

Hope that clarifies you question.
