Much of the VI you posted seems to deal with a file group with some naming scheme that increments.

The write to spreadsheet string actually opens and closes the file each time. That should be more effective and a bit more expensive than a flush on an open file. If it works, go with that. If it slows down your program too much, open it up to see how the lower level primitives are used.

If you still decide to do the file group, you basically have to step through enough instances that you trust the logic. I try to avoid the file group or keep it simple, as I seem to make a mess for myself that I have to debug whenever I attempt such a thing.
