Frequently Asked Questions
How do I convert text to uppercase?
To convert text to uppercase, simply paste your text in the input field and click the "UPPERCASE" button. All letters will be converted to capital letters instantly. For example, "hello world" becomes "HELLO WORLD".
What is the difference between Title Case and Sentence Case?
Title Case capitalizes the first letter of every word (e.g., "The Quick Brown Fox"), while Sentence Case only capitalizes the first letter of each sentence (e.g., "The quick brown fox. Jumps over."). Title Case is commonly used for headlines and titles, while Sentence Case is used for regular text.
What is camelCase and when should I use it?
camelCase is a naming convention where the first word is lowercase and subsequent words start with capital letters, with no spaces (e.g., "myVariableName"). It's commonly used in JavaScript, Java, and other programming languages for variable and function names.
What is snake_case used for?
snake_case uses underscores to separate words, with all letters lowercase (e.g., "my_variable_name"). It's commonly used in Python, Ruby, and database column names. The uppercase version (CONSTANT_CASE or SCREAMING_SNAKE_CASE) is used for constants.
What is kebab-case and where is it used?
kebab-case uses hyphens to separate words, with all letters lowercase (e.g., "my-url-slug"). It's commonly used in URLs, CSS class names, and file names because hyphens are URL-safe and readable.
