Code Case Converter

A free code case converter that turns a single identifier or phrase into camelCase, PascalCase, snake_case, and kebab-case in one click. Paste a variable name, CSS class, or sentence and see all four formats with copy buttons. Runs entirely in your browser. No server required.

Why Use This Case Converter?

• One input, four outputs: Get all common naming formats at once.
• Copy any format: Each result has its own copy button.
• Live update: Optionally convert as you type.
• Private: All conversion happens in your browser.

Key Features

• Input: One line or phrase (e.g. myVariableName, my_variable_name, or “some sentence”).
• Outputs: camelCase, PascalCase, snake_case, kebab-case.
• Copy per format: Copy any of the four results with one click.
• Word splitting: Splits on capitals, underscores, hyphens, and spaces so mixed input is handled.

How it Works

The tool splits the input into words using a regex that matches before each uppercase letter and on underscores, hyphens, and spaces. Each word is lowercased. Then it builds: camelCase (first word lower, rest title-cased), PascalCase (all title-cased), snake_case (underscore-joined), kebab-case (hyphen-joined). Consecutive capitals (e.g. HTTP) are treated as one word for splitting.
