Programming cases explained
camelCase joins words with capitalized inner words (myVariableName) and is common in JavaScript and Java. snake_case uses underscores (my_variable_name) and is typical in Python and SQL. kebab-case uses hyphens (my-variable-name) and is the standard for URLs and CSS class names. Converting between them by hand is tedious — this tool does it instantly.
Title Case vs. Sentence case
Title Case capitalizes the first letter of each major word and suits headlines and titles. Sentence case capitalizes only the first word (and proper nouns), which is the right choice for body copy, UI labels, and most modern style guides.
Frequently asked questions
What is the difference between camelCase and snake_case?
camelCase removes spaces and capitalizes each word after the first (helloWorld), while snake_case replaces spaces with underscores and lowercases everything (hello_world).
Can I convert text to a slug for URLs?
Yes — kebab-case lowercases your text and joins words with hyphens, which is exactly the format used for clean, SEO-friendly URLs.
