Case Converter

What this does

Pick a case style and the converter instantly rewrites your text. Use it to clean up copy-pasted titles, generate variable names from natural language, normalise CSV headers, or fix all-caps comments. Everything runs in your browser — your text never leaves your device.

The seven cases

• UPPER — every letter capitalised. Good for emphasis.
• lower — every letter lowercased. Good for normalising.
• Title — first letter of every word capitalised. Good for headings.
• Sentence — only the first letter of each sentence capitalised.
• camelCase — first word lowercase, subsequent words capitalised, no separators. Good for JS/Java variables.
• snake_case — all lowercase with underscores. Good for Python and DB columns.
• kebab-case — all lowercase with hyphens. Good for URLs and CSS classes.
