Text Case Converter

How to use the text case converter

Type directly into the box or paste text from anywhere — a document, a spreadsheet cell, an email, or some code. Then click the case you want and the result appears below, ready to copy.

UPPERCASE turns every letter into a capital, useful for headings or emphasis. lowercase does the opposite, handy for cleaning up text that arrived in all caps.

Capitalize Each Word capitalizes the first letter of every word. Title Case is the headline style used for titles: it capitalizes significant words but leaves small words like "and", "of", and "the" lowercase, while still capitalizing the first and last word.

Sentence case lowercases the text and then capitalizes the first letter of each sentence — the way ordinary writing looks. aLtErNaTiNg and iNVERT cASE flip letters for a stylized effect.

camelCase, PascalCase, snake_case, and kebab-case are naming styles used in programming. They remove spaces and join the words using the convention each format expects.

Everything runs in your browser — the text you type or paste is never uploaded.

Common questions

Why does camelCase remove my spaces? The programmer naming styles are designed for identifiers like variable and file names, which can't contain spaces. The converter joins the words for you using each style's separator.

Does Title Case capitalize every word? No. It follows the common headline rule of leaving short joining words lowercase, unless they are the first or last word of the title.

Can I undo a conversion? Your original text stays in the top box, so you can pick another case at any time. The result box updates each time you click a button.

Is anything saved or uploaded? No. The tool is fully client-side — your text never leaves your browser and nothing is stored.
