# casefy — Utilities for string case conversion.

License: permissive · Maintenance: aging · Downloads: 2.4M/mo

## 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 above — 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.

## Install

pip install casefy
uv add casefy
poetry add casefy

## Installing casefy

Before you install: Installs with zero runtime dependencies as a pure Python wheel. Last release was 525 days ago; the repository remains active with a recent commit on 2025-03-07, though the project is aging relative to its initial release in 2022.

License in practice: MIT License permits commercial and private use, modification, and redistribution with minimal restrictions—only requiring preservation of copyright and license notices. No compliance burden for most use cases.

Quickstart:

pip install casefy

import casefy

string = casefy.camelcase("foo_bar")
print(string)  # fooBar

string = casefy.snakecase("fooBar")
print(string)  # foo_bar
