Overview: Text Case Converter is an all-in-one case-conversion tool that supports 11 common text formats: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case and reverse. It is an indispensable helper when writing code and enforcing naming conventions.

How to use: Step 1 — paste the text you want to convert into the input box (for example Hello Data Forge World). Step 2 — the tool computes and shows all 11 formats in real time, no need to pick one. Step 3 — each format has a "Copy" button on the right that places the corresponding result on the clipboard. Step 4 — as you type, every result updates immediately so you can preview live.

Typical scenarios: Developers switch quickly between naming conventions for variables, functions, classes, constants and files; convert between database field names (snake_case) and programming names (camelCase, PascalCase); unify field names extracted from API responses; generate CSS class names (kebab-case), environment variable names (CONSTANT_CASE) or file paths (dot.case); enforce case rules across localised strings.

Technical notes: The tool splits words with the regex [a-zA-Z0-9]+, treating any other character as a separator. In camelCase the first word is lower-cased and subsequent words are capitalised; in PascalCase every word starts with an upper-case letter. Sentence case capitalises only the first letter of each sentence and lower-cases the rest. Reverse simply flips the character order without caring about word boundaries. Title Case does not apply special rules for articles or prepositions, so the result may need manual tweaking.

Privacy: All conversion happens locally in your browser and the input text is never uploaded, so it is safe to use with API field names, database columns or other business content.
