Is there a easy way to convert xbox/PC minecraft saves to PS3?

I really want to play minecraft adventure maps on my Ps3 edition of minecraft but I can only seem to find xbox or PC downloads. How do I convert them to be compatible with my PS3 and not just come up with corrupted data?

Are there any websites that have ps3 maps?

I have looked at http://www.minecraftmaps.com/, and http://www.planetminecraft.com/.../projects/

Added (1). Ok so you can't covert from PC but can you convert from xbox to ps3?

The ps3 uses completely different processing and software then a pc, so to answer your question, no its not possible:/
