casefy

What it is and what it does

Casefy is a lightweight string-casing utility that converts text between naming conventions like camelCase, snake_case, kebab-case, PascalCase, CONST_CASE, Title Case, and several others. It handles Unicode characters and offers options like keeping certain substrings together during conversion or using custom separators. The package has no third-party dependencies, making it a minimal addition to any project that needs to normalize or transform string casing—common in code generation, API design, configuration handling, and data transformation pipelines.

The API is straightforward: each casing style has a dedicated function (e.g., `casefy.camelcase()`, `casefy.snakecase()`), and most conversions work by parsing the input string into tokens and reassembling them according to the target convention. The package supports Python 3.6 through 3.13 and is marked Production/Stable, though maintenance activity has slowed since its 2022 launch.

Use it for:

• Convert API response field names from snake_case to camelCase for JavaScript clients.
• Normalize database column names to PascalCase for code generation or ORM mapping.
• Transform user input or configuration keys between naming conventions in data pipelines.
• Generate variable or function names programmatically in code generation tools.
• Standardize log output or report headers by converting identifiers to Title Case or CONST_CASE.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Casefy converts strings between different casing conventions (camelCase, snake_case, kebab-case, PascalCase, CONST_CASE, and others) with Unicode support and no external dependencies.

Yes. Casefy is a stable, zero-dependency utility that solves a common string-handling problem. Its lightweight design and broad Python version support make it a safe choice for projects needing case conversion. The aging maintenance status (525 days since last release) is not a blocker—the package is feature-complete and has no known vulnerabilities—but do not expect rapid updates if issues arise.
