Online Case Converter & URL Slug Generator
Easily convert plain text, titles, database column names, and code identifiers across all major programming case conventions. Features smart word boundary detection (acronyms, numbers, camelCase), international diacritic transliteration for clean ASCII slugs, and a batch line-by-line mode for bulk developer lists.

#Edge Cases & Technical Considerations
Consecutive Acronyms and Abbreviations
Words like "XMLHttpRequest" or "HTMLParser" are intelligently segmented into ["XML", "Http", "Request"] and ["HTML", "Parser"] rather than single character splits.
International Diacritics and Special Characters
Turkish letters (ö, ş, ç, ğ, ı, ü), German umlauts (ä, ö, ü, ß), and accented Latin characters (é, à, ñ) are safely transliterated into ASCII equivalents for URL slugs.
Mixed Alphanumeric Tokens and Numbers
Identifiers containing version numbers like "OAuth2Token" and "v1Beta" maintain natural semantic integrity across snake_case ("oauth2_token") and camelCase ("oauth2Token").
#Frequently Asked Questions
Q:What is the difference between camelCase and PascalCase?
In camelCase, the first word starts with a lowercase letter and subsequent words are capitalized (e.g., userProfileService). In PascalCase (also known as UpperCamelCase), every word including the first starts with an uppercase letter (e.g., UserProfileService), standard for classes and types in TypeScript, C#, and Java.
Q:When should I use snake_case vs kebab-case vs CONSTANT_CASE?
snake_case (user_id) is standard for Python, Ruby, and SQL column names. kebab-case (user-id) is standard for URLs, REST paths, and CSS class names. CONSTANT_CASE / SCREAMING_SNAKE_CASE (MAX_RETRY_COUNT) is standard for global constants and environment variables.
Q:Are my pasted strings or proprietary variable names uploaded to any server?
Never. All string parsing, regex tokenization, and transliteration execute 100% client-side inside your browser via an isolated Web Worker. Zero network transmissions.
