Export a project to a Jenkinsfile

Hello everyone, just started using Jenkins recently and building projects. Was wondering if theres any plugins that can take a manually created project in the UI and export it to a Jenkinsfile. Haven’t had any luck on my search so it probably doesn’t exist, but I feel like this would be a great way to help new users in writing these files.

With manually created project do you mean Freestyle projects? If yes then there is Declarative Pipeline Migration Assistant

This is perfect, thank you.
