About this tool
Different ecosystems prefer different casings: camelCase in JavaScript identifiers, snake_case in Python and SQL, kebab-case in URLs and CSS.
Title Case and Sentence case help with headings and prose. Conversion is best-effort for mixed languages and unusual punctuation.
Examples
To snake_case
Hello World Example
hello_world_example
FAQ
Will acronyms stay uppercase?
Most modes normalize to the target style, so acronyms may be rewritten (e.g. HTTP → http in lowercase modes).
