Case Converter: Free Online Tool & Complete Guide

What is the Case Converter?

Different contexts demand different text cases: sentence case for titles, camelCase and snake_case for code, CONSTANT_CASE for environment variables. Retyping or fixing case by hand is tedious and error-prone — a case converter does it in a single click.

This case converter supports ten transformations, including uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and alternating case. Paste your text, pick a style, and copy the converted result — perfect for writers and developers alike.

Frequently asked questions about the Case Converter

Here are the answers to the questions people ask most about the Case Converter.

• What is the difference between camelCase and PascalCase? — Both join words without spaces and capitalize the first letter of each word. camelCase starts lowercase (myVariable), PascalCase starts uppercase (MyClass).
• What is CONSTANT_CASE used for? — All-caps with underscores — the convention for environment variables (API_KEY), constants and preprocessor macros in most languages.
