❓ Frequently Asked Questions – Case Converter
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter and capitalizes the first letter of each subsequent word — e.g. "helloWorld" or "myVariableName". PascalCase (also called UpperCamelCase) capitalizes the first letter of every word including the first — e.g. "HelloWorld" or "MyClassName". camelCase is widely used for variables and functions in JavaScript, Java and C#, while PascalCase is typically used for class names and constructor functions.
What is snake_case and when should I use it?
snake_case replaces spaces between words with underscores and uses all lowercase letters — e.g. "hello_world" or "my_variable_name". It is widely used in Python for variable and function names, in database column names, and in file naming conventions. CONSTANT_CASE is the same but with all uppercase letters, used for constants and environment variables in most programming languages.
What is kebab-case and where is it used?
kebab-case uses hyphens between words and all lowercase letters — e.g. "hello-world" or "my-page-title". It is the standard format for URL slugs (website addresses), CSS class names and HTML attribute values. It is also used for file names in some projects. Note that kebab-case cannot be used as a variable name in most programming languages since the hyphen is interpreted as a minus sign.
What is Title Case?
Title Case capitalizes the first letter of each word in a string — e.g. "Hello World" or "The Quick Brown Fox". It is used for headings, article titles, book names and product names. Note that strict AP/Chicago Title Case rules do not capitalize short words like "a", "an", "the", "and", "but", "or" unless they start the title. This tool applies simple Title Case by capitalizing the first letter of every word.
Can I convert multiple lines or paragraphs at once?
Yes! This tool supports multi-line and multi-paragraph text. Simply paste or type your content in the input box and select the desired case. All lines and paragraphs are converted simultaneously. Cases like snake_case, camelCase and kebab-case treat each line independently, preserving the structure of your multi-line input. The output preserves line breaks where appropriate.
