Case Converter

When to use Case Converter

A developer exported a database column and every value came back in ALL_CAPS_SNAKE_CASE, but the API they are building expects camelCase. Paste the list here, click camelCase, and the conversion happens through JavaScript string methods — no server involved, no waiting. The same workflow applies when a designer pastes a page of copy into Figma and the headlines are a mix of sentence case and random caps, or when a writer inherits a document where someone typed every subheading in UPPERCASE. Pick the target style — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case — and the output is ready to copy in one click. Everything runs on your device with no upload, so pasting confidential data is fine.

• Convert a database export from ALL_CAPS to camelCase for an API
• Fix inconsistent headline casing in a pasted blog draft
• Turn a list of variable names from snake_case to kebab-case

About this tool

Copy something out of one system and the casing is wrong for the next: a spreadsheet column full of ALL CAPS names, a code variable that needs snake_case, a headline that should be Title Case but isn't. Paste your text and switch between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, and more in one click. Works on any length — a single word or a thousand lines. Your text stays on your device, no upload happens, and there's no account required. Useful for developers normalizing identifiers, writers cleaning up pasted content, and anyone dealing with inconsistent data.
