Text Case Converter

Title Case capitalizes the first letter of all major words while keeping minor words (articles, conjunctions, and prepositions like "a", "an", "the", "and", "but", "for", "to", "in") in lowercase. Capitalize Words capitalizes the first letter of every single word in the text without exception.

camelCase is a variable naming convention where words are combined without spaces, and each word starts with a capital letter except for the very first word. Example: "camelCaseConverter". It is heavily used in JavaScript, Java, and other programming languages.

snake_case replaces spaces between words with underscores (_) and converts all letters to lowercase. Example: "snake_case_converter". It is widely used in Python variables, database field names, and JSON keys.

kebab-case (also known as spinal-case or dash-case) replaces spaces with hyphens (-) and converts all letters to lowercase. Example: "kebab-case-converter". It is standard for URL slugs, HTML class/ID names, and CSS selectors.

iNVERSE cASE swaps the capitalization of every single character: uppercase letters become lowercase, and lowercase letters become uppercase. It is useful for correcting text typed accidentally with Caps Lock on.

Sentence Case capitalizes only the first letter of each sentence and proper nouns, converting the rest of the text to lowercase. Sentences are identified by punctuation marks like periods, exclamation marks, or question marks.
