How to use this tool

Changing the case of text is a common task: renaming a title, formatting an identifier, cleaning an Excel import. Instead of retyping or using a macro, paste your text and copy the variant you want in one click. The tool handles accents and Unicode correctly.

Concrete examples

• "Hello World" → "hello_world", "hello-world", "HELLO_WORLD"
• "my variable name" → "myVariableName" (camelCase)
• "Title Of My Article" → "title-of-my-article" (URL kebab-case)

Frequently asked questions

Difference between camelCase and PascalCase?

Both drop spaces and capitalize each word. camelCase keeps the first word lowercase (myVariable); PascalCase capitalizes it too (MyVariable, typical for class names).

What is snake_case?

Words joined by underscores, all lowercase ("my_identifier"). Common in Python, SQL and filenames.

Why kebab-case for URLs?

Google treats hyphens as word separators; underscores are not. kebab-case makes URLs both readable and SEO-friendly.
