What is the difference between camelCase and snake_case?

camelCase joins words by capitalising each word after the first, with no separator (e.g. myVariableName). snake_case joins words with underscores in all lowercase (e.g. my_variable_name). camelCase is common in JavaScript; snake_case is standard in Python.

Does Title Case capitalise every word including 'and', 'the', 'of'?

Yes. The current implementation capitalises every word. It does not apply AP or Chicago style rules that leave short prepositions and articles in lowercase.

Are numbers and punctuation affected?

No. Only alphabetic characters are changed. Numbers, punctuation, and symbols pass through unchanged.

Is there a character limit?

No hard limit. The tool handles large blocks of text — entire code files or long articles — without issue.

About Case Converter

Accidentally typed a paragraph with Caps Lock on? Need to rename a batch of variables from camelCase to snake_case? This Case Converter handles six distinct casing formats in one click: UPPERCASE, lowercase, Title Case (every word capitalised), camelCase (first word lowercase, subsequent words capitalised, no spaces), snake_case (all lowercase joined by underscores), and kebab-case (all lowercase joined by hyphens). The conversion is applied to the entire input at once — paste a full function name, a heading, or a block of copy and switch formats instantly. Non-alphabetic characters like numbers, punctuation, and symbols are preserved exactly as entered. Developers use it most for normalising variable names and API keys; writers use it to fix accidental caps lock or format article titles consistently. The result appears in a second textarea so you can compare before copying.
