The Case Converter transforms text between 10 different case formats with one click: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and tOGGLE cASE. Whether you're formatting variable names in code, converting headings for documents, or standardizing text data, this tool handles it instantly. Paste your text, click the case you want, and copy the result. All processing happens locally in your browser - nour text is never stored or transmitted.
Type or paste the text you want to convert into the input area. The tool works with any text: sentences, variable names, titles, or multi-line content.
Click one of the 10 case format buttons to convert your text. Hover over any button to see an example of that case format. The active format is highlighted.
The converted text appears in the output area. Click 'Copy Output' to copy it to your clipboard for use in your code, documents, or wherever you need it.
Click any other case button to switch formats instantly. The conversion always applies to your original input text, so you can compare different formats easily.
camelCase starts with a lowercase letter and capitalizes each subsequent word (myVariableName). PascalCase capitalizes every word including the first (MyVariableName). In programming, camelCase is typically used for variables and functions, while PascalCase is used for class names and type definitions.
snake_case (words_separated_by_underscores) is the convention in Python, Ruby, and database column names. kebab-case (words-separated-by-hyphens) is used in URLs, CSS class names, and HTML attributes. Use whichever matches your project's conventions.
CONSTANT_CASE (all uppercase with underscores) is the convention for constant values in most programming languages: MAX_RETRY_COUNT, API_BASE_URL, DEFAULT_TIMEOUT. It visually distinguishes constants from variables, signaling that these values should not be changed.
Title Case capitalizes the first letter of every word (The Quick Brown Fox). Sentence case capitalizes only the first letter of each sentence (The quick brown fox). Title Case is used for headings and titles, while Sentence case is used for normal text.
Yes, the converter preserves numbers and most special characters. When converting to programming cases (camelCase, snake_case), words are split on spaces, hyphens, and underscores. Numbers are treated as part of the word they're attached to.
