I work in a correctional centre. Some of the correctional officers have
little training to use Excel or other programs, but are required to complete
spreadsheets on line. Although we have heavily protected the worksheets and
locked cells, we find that in some cases the staff can still mess up the
worksheets by copying and pasting data inappropriately.

Is there a way to turn off the ability to paste data into the worksheet, and
to force each field to be completed manually? This would eliminate the
problem.
