This is quite easy if you are happy recording a macro. Basically, highlight the top left cell, turn on macro recording (relative references), and then insert two rows below, and cut and paste E and F into their new positions. Highlight the second cell A and then stop the recording.
Go into the macro editing bit and put a 'For i = 1 to 600' line first and 'Next i' at the end. Run the macro and everything should work.
You need to know about a bit of macro stuff to do this, but it will work a charm. Good luck
