How It Works
This tool converts any text between the case conventions used in writing (UPPERCASE, Title Case) and the naming conventions used in code (camelCase, snake_case, kebab-case), so you don't have to retype or manually reformat text by hand.
Writing cases vs. programming cases
UPPERCASE, lowercase, Title Case, and Sentence case are formatting conventions for readable text. camelCase (firstWordLower, restCapitalized), PascalCase (AllWordsCapitalized), snake_case (words_with_underscores), and kebab-case (words-with-hyphens) are naming conventions used in code for variables, functions, files, and URLs — each programming language or context typically favors one specific convention.
Examples
Converting a variable name
"user first name" becomes userFirstName (camelCase), UserFirstName (PascalCase), user_first_name (snake_case), or user-first-name (kebab-case) depending on what your codebase's style guide requires.
Converting a heading
"the quick brown fox" becomes "The Quick Brown Fox" in Title Case, or "THE QUICK BROWN FOX" in uppercase.
Common Use Cases
- Converting variable or function names between camelCase, snake_case, and PascalCase when switching between programming languages with different style conventions
- Formatting headings or titles into consistent Title Case for documents or web content
- Converting text case for filenames, URLs (kebab-case), or database column names (snake_case)
Tips
- Different languages have different conventions: JavaScript/Java typically use camelCase for variables, Python typically uses snake_case, and many CSS/URL contexts use kebab-case — match your target codebase's existing style rather than personal preference.
- Title Case rules vary slightly by style guide (some keep short words like "a", "the", "of" lowercase unless they start the title) — this tool capitalizes every word, so double-check against your specific style guide for formal writing.
