It almost certainly would be useful for someone other than you.
Everything you described automating is something at least thousands of people also do. And most of them don't care about the code quality if it works.
Still, the code lives in a git repo, so it's not excluded that I'll make it evolve to something more generic and maintainable in the future. But today, it's my own little dirty code that I will jealously keep and hide like that lewd drawing I did when I was a teenager.
