Template base excel export

TMS FMX Grid ExcelIO is working well but when we export data to excel sometimes we need excel Template for formatting.
We can make it on windows with open template excel file write the data in the grid and save as it. But it should be in the grid.
That is very useful for program users.

You can use templates with TMS FMX Grid. Can you explain a little more what would this new templates do and what would be different from the current way?
