Can you transfer a part of a world into another world?

Sorry if this is not the right place for this question, I thought it would be a little too technical for r/Minecraft and I don't know a better sub for it

One of my longest running worlds got corrupted (I don't have a backup) and I started a new one that I've been playing for a while now. Is there a way to cut some parts of my corrupted world and move it to my current one?

The part I want to transfer is like a 15x15 chunk area, I don't care about chunk borders, I'm gonna paste my build in an ocean and I can smooth those parts out
