Formula
Six transformations are available: UPPERCASE, lowercase, Title Case, camelCase, snake_case, and kebab-case. Each transformation applies consistent rules to convert the input text.
Worked example
Input "Hello World" → UPPER: "HELLO WORLD", lower: "hello world", Title: "Hello World", camel: "helloWorld", snake: "hello_world", kebab: "hello-world".
Practical guidance
Programming conventions
camelCase is used in JavaScript/TypeScript for variables and functions. snake_case is common in Python, Ruby, and database column names. kebab-case is used in CSS class names and URLs. Use the appropriate converter for your codebase.
Title Case rules
The Title Case converter capitalizes the first letter of each word and lowercases the rest. Note that style guides disagree on whether to capitalize short words like "a", "the", "in". This converter capitalizes every word for simplicity.
