Frequently asked questions
What is camelCase?
A naming style where words are joined without spaces and each word after the first starts with a capital, like myVariableName.
Can I convert from camelCase to snake_case?
Yes. The tool understands camelCase, snake_case, kebab-case and plain words, so you can switch between them.
What does the slug option do?
It makes a clean web address from a title: lower case, no accents or symbols, words joined by dashes.
Are my files uploaded anywhere?
No. This tool runs in your browser, so your file stays on your device and is never sent to a server.
