What is snake_case?
snake_case joins words with underscores, all lowercase: "user profile page" becomes "user_profile_page". It is the conventional style for Python variables, Ruby methods and SQL column names.
Can I convert a list of names at once?
Yes — each line converts independently, so a pasted list of headings or labels becomes one snake_case identifier per line.
