Frequently Asked Questions
camelCase writes compound words without spaces, capitalizing the first letter of each word after the first (e.g., myVariableName). It's the convention in JavaScript, Java, Swift, and many other languages for variables and function names.
Both remove spaces and capitalize word boundaries, but PascalCase (UpperCamelCase) capitalizes every word including the first — MyClassName — while camelCase starts lowercase — myClassName. PascalCase is for class names; camelCase is for variables and functions.
snake_case (underscores) is the Python standard and is common in SQL and Ruby. kebab-case (hyphens) is used in CSS class names, HTML attributes, URLs, and CLI flags. They're both "all lowercase" formats — the only difference is the separator character.
Yes. The converter splits on spaces, hyphens, underscores, and camelCase/PascalCase boundaries so it correctly converts from any format to any other. For example, pasting "myVariableName" will correctly output "my_variable_name" in snake_case.
