What is a case converter?
A case converter rewrites your text into a chosen capitalisation or naming convention. Developers use it to switch identifiers between camelCase, snake_case and kebab-case; writers use it for headings and titles. This tool detects word boundaries — including existing camelCase — and reformats instantly.
