How to use this tool
- Paste the text you want to transform.
- Choose a prose case or naming style such as camelCase, snake_case, or kebab-case.
- Run the conversion and review abbreviations and proper names before copying.
Formula & method
Upper and lower case use locale-aware conversion. Title case capitalizes word starts. Code-style modes split words and join them with camel, Pascal, underscore, or hyphen conventions. Scripts without letter case remain unchanged.
A practical example
Hello world becomes helloWorld in camelCase, HelloWorld in PascalCase, and hello_world in snake_case.
When this tool is useful
Normalize a heading, prepare a code identifier from a phrase, or convert a list of names to a consistent naming convention. The appropriate mode depends on whether spaces and punctuation should remain part of the output.
Common mistakes and limitations
- Title case is a mechanical capitalization rule, not a full editorial style guide.
- Code-style modes tokenize text and can remove punctuation; retain the original if punctuation is meaningful.
Frequently asked questions
Will the tool preserve acronyms automatically?
No. Mechanical case conversion can change API to Api or api depending on the mode. Review acronyms, product names, and other intentional capitalization.
Why does some text remain unchanged?
Some writing systems do not have upper- and lowercase letter forms. Case operations cannot create distinctions that do not exist in the script.
