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.

Ctrl A: Select All cells.
Ctrl C: Copy selection which is available for paste.
Ctrl X: Cut selection which is available for paste.
