Here is my problem. I have data for example C1:D200.

All of C1:C200 have values in but only certain cells in D1:D200 have values
in them.

Is it possible to create a macro that will delete the rows for a certain
selection where D have no values in?

Also - after this has been done and there are say 20 values in each column
of C1:D20 is it possible to insert say 200 blank rows after each value. (eg
C1 has value, D1 has value, C201 has value, D201 has value etc...)

Thanks
