[help_for_excel]

Hi,

I have power-point file which has 2500 slides and I want to create new power-point file with selected number of slides lets say 20 slides from 2500. Which I can control it from Excel VBA (For simplicity I have mentioned number 1 to 2500 in excel and I can select any 20 numbers and new powerpoint file will be created.)

Any codes, any references etc will helpful.

Thanks in advance.
