textcase
Python library for text case conversions.
Decision gist · record as of 2026-08-14
Yes. textcase is lightweight (zero dependencies), actively maintained, well-tested, and solves a common string-manipulation task cleanly. Install it if you need reliable case conversion; the low friction and permissive license make it a safe addition to any project.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
textcase is a pure-Python library for converting strings between different text case formats—snake_case, kebab-case, camelCase, PascalCase, CONSTANT_CASE, and others. It handles word boundary detection automatically, including acronyms (e.g., "HTTPRequest"), non-ASCII characters, and punctuation, without requiring regex or external dependencies. The library is fully type-annotated and carries 100% test coverage.
You import it and call functions like `textcase.snake()`, `textcase.camel()`, or `textcase.pascal()` on any string. It's useful when you need to normalize identifiers across different naming conventions—for instance, converting API response field names to Python variable names, or generating code identifiers from user input. With zero dependencies and a small footprint, it's safe to add to any project.
Use it for
- Convert API response field names (often snake_case) to camelCase for JavaScript or PascalCase for C#
- Generate valid Python variable or function names from user-provided strings or external data
- Normalize configuration keys or environment variable names across different naming conventions
- Transform database column names to match code style conventions in ORM or data mapping layers
- Build code generators or template systems that need to adapt identifiers to target language conventions
