Text Case Converter

This tool converts your text into every common letter case at once, from UPPERCASE and lowercase to Title Case, Sentence case, camelCase, snake_case and kebab-case, so you can grab whichever one you need. Changing the case of text by hand is tedious and error-prone, especially for headings, code identifiers, file names and slugs, and retyping a whole block just to capitalise it differently is a waste of time. This converter does it instantly. You paste your text, and it shows the same words rendered in each case style side by side, ready to copy. Each style suits a different job. UPPERCASE and lowercase are self-explanatory and useful for shouting or normalising text. Title Case capitalises the first letter of each word, the convention for headings and titles. Sentence case capitalises only the first letter of each sentence, as in ordinary prose. The remaining three are the naming conventions programmers use: camelCase joins words with a capital at the start of each after the first and no spaces, the standard for variables in many languages; snake_case joins words with underscores in lower case, common in Python and database columns; and kebab-case joins them with hyphens, the usual choice for web addresses and CSS classes. The conversion updates as you type, so you can paste, tweak and copy in seconds. Use it to fix the capitalisation of a heading, to turn a label into a code-friendly identifier, to standardise data, or to convert a phrase into a clean slug. Everything runs in your browser, so your text is never uploaded anywhere.

Shows all seven common cases at once. camelCase, snake_case and kebab-case are the naming styles used in code. Runs entirely in your browser.
