Text case conversion is the process of transforming text between different capitalization formats. This includes converting text to uppercase, lowercase, title case, and various programming conventions like camel case, snake case, and kebab case.
Different case styles serve different purposes - from improving readability in documents to following specific naming conventions in programming languages and databases.
Converts all characters to capital letters. Commonly used for headings, emphasis, and acronyms.
Example: "hello world" → "HELLO WORLD"
Converts all characters to small letters. Used for normal text, URLs, and file names.

It depends on your programming language and team conventions. JavaScript typically uses camelCase for variables and PascalCase for classes. Python uses snake_case, and CSS often uses kebab-case.
Yes! Use the "Convert All Cases" button to generate all case variations simultaneously. This is useful for comparing different formats or generating multiple versions.
Yes, special characters, numbers, and punctuation are preserved during conversion. Only alphabetic characters are affected by case changes.
The tool can handle large amounts of text, but very long texts may take longer to process. For best performance, consider converting text in smaller chunks if needed.
