String Case Converter

Convert strings between camelCase, snake_case, kebab-case and more. Free case converter.

What is a Case Converter?

A case converter transforms text between different naming conventions used in programming, writing, and data formatting. Every programming language and context has its own preferred casing style. JavaScript and Java use camelCase for variables and functions. Python and Ruby prefer snake_case. CSS and HTML attributes use kebab-case. Environment variables and constants are written in CONSTANT_CASE. PascalCase is standard for class names in most languages. This tool converts your input into all 11 common case formats simultaneously, saving you the time and effort of manual conversion. It correctly handles multi-word strings, existing cased text, and mixed separators.

How to Use This Tool

Type or paste any text into the input field. The tool instantly converts your input into camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, path/case, Sentence case, Capital Case, no case, and Train-Case. Each result has a copy button so you can grab the exact format you need. The converter intelligently detects word boundaries from spaces, hyphens, underscores, camelCase transitions, and other separators, so it works whether you input "hello world", "helloWorld", "hello-world", or "HELLO_WORLD".

Common Use Cases

  • Converting variable names when porting code between JavaScript (camelCase) and Python (snake_case)
  • Generating CSS class names in kebab-case from component names written in PascalCase
  • Creating environment variable names in CONSTANT_CASE from descriptive labels
  • Converting database column names between snake_case and camelCase for ORM mapping

Why Use a Client-Side Tool?

This case converter runs entirely in your browser with no server requests. Your text, which may include variable names, proprietary code identifiers, or internal naming conventions, never leaves your device. The conversion happens instantly as you type, with zero latency. There are no API limits, no account requirements, and the tool works offline once loaded. This makes it safe and fast to use during active coding sessions when you need quick case transformations.

Frequently Asked Questions

What case formats does this tool support?

This tool supports 11 case formats: camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, path/case, Sentence case, Capital Case, no case, and Train-Case. All formats are generated simultaneously from a single input, so you can compare and pick the one you need.

Which case convention should I use for my project?

The best convention depends on your language and context. JavaScript and TypeScript use camelCase for variables and PascalCase for classes and components. Python uses snake_case for variables and functions. CSS uses kebab-case for class names and properties. Environment variables use CONSTANT_CASE. Most importantly, be consistent within your project and follow your team or framework conventions.

Can this tool handle multi-word input with mixed separators?

Yes, the converter intelligently detects word boundaries from spaces, hyphens, underscores, dots, slashes, and camelCase transitions. Whether you input "my variable name", "my-variable-name", "myVariableName", or "MY_VARIABLE_NAME", the tool correctly identifies the individual words and converts them to all supported formats.
