Case Converter

The Smart Case Converter by CleanFormatter is a next-generation text transformation tool designed for writers, developers, bloggers, editors, and content creators who need precise and reliable case formatting. Unlike traditional case converters that merely flip text to upper or lower case, this tool uses a PRO-level engine that understands protected words, industry acronyms, brand-specific casing, and user-defined ignore lists. This ensures that critical terms such as NASA, API, ChatGPT, JavaScript, or custom brand names remain unaffected by formatting rules. With support for 15+ powerful case formats—including Title Case, Capitalization Case, Sentence case, camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case, and path/case—the tool adapts to both editorial and development workflows. The built-in linguistic engine respects grammar rules, avoids over-capitalization, handles small-word exceptions, processes hyphenated words, and intelligently reconstructs multi-word phrases. <p></p>The tool also includes quality-of-life features such as whitespace cleanup, duplicate line removal, line sorting, code-friendly formatting, and a fully customizable ignore-word system. Whether you're preparing blog content, writing documentation, formatting product descriptions, optimizing SEO titles, or generating programming identifiers, the Smart Case Converter ensures accuracy, consistency, and readability across every output. With its clean UI, instant output, and highly tuned transformation engine, this tool becomes an essential part of any writer or developer’s productivity toolkit.
