Technical Details
The case converter handles various edge cases: Title Case capitalizes the first letter of every word, Sentence Case only capitalizes after sentence-ending punctuation. Programming cases (camelCase, PascalCase, snake_case, kebab-case) properly handle word boundaries including spaces, hyphens, and existing mixed-case patterns. Non-alphanumeric characters are treated as word separators for code case conversions.
Frequently Asked Questions
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word (e.g., 'Hello World'), while Sentence case only capitalizes the first letter after a period or at the beginning (e.g., 'Hello world').
When should I use camelCase vs PascalCase?
camelCase starts with a lowercase letter and is used for variable names in JavaScript/Java. PascalCase starts with an uppercase letter and is used for class names and React components.
Does it handle special characters and accented letters?
Yes, the converter handles accented characters and most Unicode letters. Special characters and numbers are preserved and treated as word separators in code case conversions.
