Frequently Asked Questions
Everything you need to know about Case Converter and how it works.
Case Converter supports 14 formats: UPPER CASE, lower case, Title Case, Sentence case, camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case, TRAIN-CASE, dot.case, path/case, aLtErNaTe CaSe, and iNVERSE cASE. Together these cover the full range of formats used in writing, programming, content creation, and social media.
No. All text conversion happens entirely within your web browser using client-side JavaScript. Your text is never transmitted to any server, never stored in any database, and never shared with any third party. When you close or refresh the page, your text is gone completely. This makes Case Converter safe to use with confidential code, private documents, and sensitive content.
The tool processes one block of text at a time, but the workflow is fast: paste your text, click a format, copy the result, then paste the next piece of text. For bulk work, you can also use the Download button to save converted text as a .txt file so you can accumulate results locally without losing them between conversions.
Both formats remove spaces and capitalize each word boundary, but they differ in how they treat the very first word. In camelCase, the first word is entirely lowercase: helloWorld. In PascalCase, the first word is also capitalized: HelloWorld. In practice, camelCase is typically used for variable and function names in JavaScript, Java, and C#, while PascalCase is used for class names, constructors, React components, and TypeScript interfaces.
A URL slug is the part of a web address that identifies a specific page in a human-readable way. For example, in the URL example.com/blog/how-to-write-better, the slug is "how-to-write-better". Slugs should be lowercase, use hyphens to separate words, and contain no spaces or special characters. The kebab-case format is the correct format for generating URL slugs, and Case Converter will transform any title or phrase into a properly formatted slug instantly.
