Text Case Converter
A text case converter transforms your text between uppercase, lowercase, title case, camelCase, snake_case, and other formatting styles instantly. Developers switch variable naming conventions, writers format headings, and marketers normalize titles without retyping everything. The tool runs entirely in your browser so no text leaves your device. Paste any content and choose the target case to get a clean, ready-to-use result in one click. The converter applies Unicode-aware string transformations to your input. Uppercase mode capitalizes every character, lowercase lowercases them, and title case capitalizes the first letter of each word. Programming formats like camelCase, PascalCase, snake_case, and kebab-case are produced by splitting words on boundaries and rejoining them with the chosen separator. All processing happens locally with no network calls. Common use cases: Reformatting code variable names between naming conventions. Preparing article headlines and book chapter titles. Cleaning up all-caps text from forms and emails. Converting CSV header rows to snake_case for databases. Standardizing filenames before deployment. Fixing inconsistent capitalization in imported spreadsheets.
