textcase

textcase is a lightweight, performant Python library designed for comprehensive text case conversions. It supports a wide array of cases like snake_case, kebab-case, and camelCase, and handles complex word boundaries including acronyms and non-ASCII characters. The library is notable for having zero external dependencies and a strong focus on accuracy and extensibility. It is actively maintained with frequent releases, with the current version 0.4.5, released in October 2025, ensuring Python 3.14 compatibility.
