What Is a Case Converter?

A case converter changes the capitalisation and formatting of text without changing the words themselves. Instead of manually retyping a sentence to fix its capitalisation, or renaming a variable by hand to match a coding convention, a case converter does it instantly - useful for everything from tidying up a heading to preparing text for a spreadsheet, a piece of code, or a URL.

Types of Text Case

UPPERCASE

Every letter capitalised, e.g. HELLO WORLD - often used for emphasis or headings.

lowercase

No capital letters at all, e.g. hello world.

Title Case

The first letter of each word capitalised, e.g. Hello World - common for headings and titles.

Sentence case

Only the first letter of each sentence capitalised, e.g. Hello world. This is a test. - the normal way most prose is written.

camelCase

Words joined with no spaces, first word lowercase and every following word capitalised, e.g. helloWorld - common for variable names in programming.

snake_case

Words joined with underscores, all lowercase, e.g. hello_world - common in programming and database field names.

kebab-case

Words joined with hyphens, all lowercase, e.g. hello-world - common in URLs and file names.

When Is a Case Converter Useful?

Writers and students use it to fix accidental caps-lock text or format a title correctly. Bloggers and content creators use it to keep headings consistent across a site. Social media users use it to make a post stand out with a different case style. Office workers use it to tidy up text copied from another document or spreadsheet. Developers and programmers use it to convert plain text or phrases into the camelCase, snake_case, or kebab-case naming conventions their code or file names require.
