Running MS Excel in background OR minimized.

Is there a way to run macros in the background? I currently have several hundred VBA macros (Only coding language available to our company) integrated into a private application used for program delivery. Every time a macro is run, excel has to open up.

I know VBA uses the application, so it has to open - but is there a way to keep excel in the background or keep it minimized so users can't see it?


Also many of the macros use user forms. Will this impact excels visibility if the above is possible?


Thanks for everyone's help.
