About CaseConvert

CaseConvert is a free, browser-based case converter that transforms text between uppercase, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, alternating case, and inverse case — in a single click.

Why we built it

Developers, writers, editors, and data analysts constantly retype identifiers and headlines by hand to match a specific casing convention. A database column arrives as user_first_name and needs to become userFirstName in JavaScript, user-first-name in CSS, and UserFirstName as a React component. Doing that by hand is slow and error-prone. We wanted a tool that does all of it in one click, never uploads your text, and costs nothing.

How it works

Each conversion mode is a small, well-tested JavaScript function running in your browser. The word-based cases (camelCase, snake_case, kebab-case, and friends) first split your text on spaces, underscores, hyphens, and camelCase boundaries, then rejoin the words in the target style. Title Case follows AP/Chicago-style rules: short articles, conjunctions, and prepositions stay lowercase unless they are the first or last word. Everything runs locally — no server round-trip.
