Copy paste functionality of ParamQuery is compatible with MS Excel i.e., data can be copied from ParamQuery Grid and pasted to MS Excel and vice versa.
For MAC: Use Command key instead of Ctrl key on Mac for copy paste operations.
Cut/copy done with Ctrl / Command keys are clipboard operations and can be accessed by other applications like Excel.
Cut/Copy done with click of a button are not clipboard operations, hence not available to other applications.
The pasted data can be customized with beforePaste event, for example to convert external formatted data into valid number or date values.
