Frequently Asked Questions

What is title case?+
Title case capitalizes the first letter of each major word and leaves articles, prepositions, and conjunctions (like "a", "in", "and") lowercase, unless they start the title. Example: "The Art of War".
What is camelCase vs PascalCase?+
camelCase starts with a lowercase letter and capitalizes subsequent words: myVariableName. PascalCase (also called UpperCamelCase) capitalizes every word including the first: MyVariableName. camelCase is common in JavaScript; PascalCase is used for class names and React components.
Does it work with accented characters?+
Yes. The converter correctly handles accented letters like é, ñ, ü, and other Unicode characters common in European languages.
