I've never needed to do this before. What is the best way to do it?
More info on how it's set up? Are the pages individual or has it been set to the spread size?
If it's in individual pages but appears as spreads, you can just turn off 'facing pages' in the document setup.
I think you've misunderstood what I want, I have a 50 page document that I want to turn into 50 InDesign documents. Unless I'm dreaming there is a way to do it, probably with a script.
Loic Aigon offers free script for it - Pages Extractor:
frankly, didn't tested it myself...
