How to format copied code under ESLint?

Question

JavaScript

I use Nuxt, it uses ESLint babel-eslint. I'm used to fixing everything with pens, every space, and so on.
But now it was necessary to copy a lot of someone else's code into the project, and there is generally different formatting, semicolons, tabs, and so on.
How to bring this code in order under these rules? Is there a plugin for this?
