# case-converter — A string case conversion package.

License: permissive · Maintenance: aging · Downloads: 487.4K/mo

## What it is and what it does

case-converter is a lightweight string transformation library that converts text between standard naming conventions. It handles camelCase, snake_case, kebab-case, PascalCase, MACRO_CASE, flatcase, cobolcase, and titlecase conversions. The package intelligently identifies word boundaries using configurable delimiters (default: space, hyphen, underscore) and handles edge cases like consecutive uppercase letters and punctuation.

You use it by importing a conversion function and passing a string, optionally with parameters to control punctuation stripping and custom delimiters. It has no external dependencies and installs as a pure Python wheel, making it suitable for any project needing reliable case normalization—common in API clients, configuration tools, and code generation.

Use it for:

- Normalize API request/response field names between camelCase (JavaScript) and snake_case (Python) conventions
- Generate variable or function names programmatically from user input or configuration strings
- Convert database column names or identifiers between different naming styles for compatibility
- Build code generators or templating tools that need to output identifiers in target language conventions
- Standardize configuration keys or environment variable names across systems with different naming rules

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Converts strings between different naming conventions (camelCase, snake_case, kebab-case, PascalCase, MACRO_CASE, and others) with configurable delimiters and punctuation handling.

Yes. The package is stable, dependency-free, and solves a common string-handling task with no security vulnerabilities. Install it if you need case conversion; the only caveat is that updates are infrequent, so verify it handles your specific edge cases before relying on it in production.

## Install

pip install case-converter
uv add case-converter
poetry add case-converter

## Installing case-converter

Before you install: Low install friction with no runtime dependencies. Package is in Production/Stable status but aging—last release was 541 days ago, though the repository remains active and not archived.

License in practice: Licensed under MIT (permissive), so you can use, modify, and distribute the package freely with minimal restrictions.

Quickstart:

pip install case-converter

from caseconverter import camelcase, snakecase

camelcase("Hello, world!")  # output: helloWorld
snakecase("Hello, world!")  # output: hello_world

Verify before relying:

- Whether the package supports modern Python versions (requires_python is unspecified in metadata)
- Whether updates are planned or the aging status indicates the package is in maintenance-only mode
