What is a case converter?
A case converter changes the capitalisation of text without changing the words themselves. Writers use it to fix headings typed in the wrong case, students use it for titles, and developers use it to turn plain phrases into variable names like camelCase and snake_case.

The case styles, in plain words
- UPPERCASE — every letter capital. Good for warnings and short labels, hard to read in long text.
- lowercase — no capitals at all. Common in web addresses and code.
- Title Case — the first letter of every word is capital. Used for headlines and book titles.
- Sentence case — only the first letter of each sentence is capital, like normal writing.
- aLtErNaTiNg case — letters take turns being capital and small. Mostly for fun and social posts.
- camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE — naming styles programmers use for variables and files.
