Overview
What does Case Converter do?
Type or paste text, choose a target case, and the tool returns the converted version. Supported formats: title case (each word capitalized), sentence case (first word capitalized), camelCase (no spaces, capitalizing each word after the first), and snake_case (lowercase with underscores).
The default output is title case; switch formats with the option selector.
Under the hood
How does it work?
The tool splits your text into words on spaces, underscores, and hyphens. Each format then joins those words differently: title capitalizes every word, sentence capitalizes only the first, camel lowercases the first word and capitalizes the rest, and snake lowercases everything and joins with underscores.

Technical information
How the details work
Words are extracted by splitting on whitespace, underscores, and hyphens. Title case capitalizes each word's first letter and lowercases the rest; sentence case capitalizes only the first word; camel case lowercases the first word and capitalizes subsequent words; snake case lowercases all words and joins with underscores.
