Perguntas frequentes

Is my data safe?
Yes. All processing happens entirely in your browser. Your data never leaves your device and is never uploaded to any server.
What case formats are available?
camelCase, PascalCase, snake_case, kebab-case, UPPER CASE, lower case, Title Case, and Sentence case are all supported.
Can it convert an entire paragraph at once?
Yes. Paste any amount of text and click the case button. The entire text is converted, preserving spaces, line breaks, and punctuation.
How does the converter handle mixed-case input like camelCase?
When converting from camelCase or PascalCase to another format, the converter splits on uppercase letter boundaries. For example, 'myVariableName' splits into 'my', 'variable', 'name' before reassembling in the target format.
Does it handle acronyms correctly?
Acronyms in all caps (e.g., 'API', 'URL') are treated as single words in most conversion modes. This matches the convention used by most style guides and linters.

Casos de uso de Case Converter

Variable and function renaming

Convert a list of plain English terms to camelCase or snake_case for use as variable names, function names, or object keys.

Database column names

Standardize column names from Title Case or sentence case to snake_case, which is the conventional format for SQL database columns.

Blog post titles

Apply Title Case consistently to article headings. Title Case has specific rules about which words are capitalized — the converter handles them automatically.

CSS class names

Convert descriptions to kebab-case, the standard convention for CSS class names and HTML attributes (e.g., 'main header' to 'main-header').

Dicas e boas práticas

  • 💡Paste a list of words separated by newlines to batch-convert all of them in one operation.
  • 💡Title Case capitalizes the first letter of most words but not articles (a, an, the) or short prepositions (in, on, at) — consistent with AP and Chicago style.
  • 💡For code, always double-check that converted names do not accidentally create reserved keywords in your programming language.
  • 💡Sentence case capitalizes only the first letter of the first word and proper nouns, making it ideal for UI labels and error messages.

Como se compara

Most code editors (VS Code, IntelliJ) have plugins for case conversion, but they require installation and only work within the editor. This tool works anywhere in your browser and is especially useful when you are outside your editor — drafting in a document, renaming spreadsheet columns, or preparing content for a CMS that requires specific naming conventions.
