Frequently Asked Questions
What is Title Case?
Title Case capitalizes the first letter of each word. Some style guides exclude small words like "the", "a", "in" but our converter capitalizes all words for consistency.
What is camelCase used for?
camelCase is the standard naming convention for variables and functions in JavaScript, Java, and many other languages. First word lowercase, subsequent words capitalized.
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (myVariable), while PascalCase starts with an uppercase letter (MyVariable). PascalCase is used for class names.
When should I use snake_case?
snake_case is standard in Python, Ruby, database columns, and API parameters. Words are lowercase and separated by underscores.
Does it handle special characters?
Yes. Special characters and numbers are preserved in text cases. For programming cases (camelCase, snake_case), special characters are removed.
Is my text stored?

Is it free?
