Hi Baron,
The copydata X-Function does not change the column types in the output range. But for the colcopy X-Function, there is an option format. If you set it to 1, the formats including column types of source columns will be applied to the destination columns. So you can use the following script command, if you want to duplicate the column formats:
colcopy irng:=A[1]:B[200] orng:=Sheet1!1:2 par:=1 format:=1
