A heading that arrived in ALL CAPS, or a column that must become snake_case. English-centric transforms. Slugs are a different page.

A ticket title in shouty caps, a CSV header that must become order_id, a JSON key that a stylebot wants in camelCase. This page rewrites letters and separators. It is not a copy desk.

URL paths belong on slugify. Cleaning extra spaces first can help: whitespace cleaner. Fancy Unicode fonts are fancy text and will break search.

Identifiers vs prose

API fields that flip between userId and user_id belong here. A blog title that must become a URL slug belongs on slugify. Unicode titlecase is best-effort; Turkish i / İ and small caps will not match Chicago Manual. Do not use this as a linter or a legal style guide.

How to use it

  1. Paste the string.
  2. Pick the transform. Glance at particles (“van”, “Mc”) by eye.
  3. Copy. Do not treat the result as a legal style-guide pass.

Honest limits

Not ICU complete titlecase. Not a programming-language rename refactor across a repo.

FAQ

Is title case Chicago or AP?

Neither, fully. Small words (of, and) may or may not stay lower depending on the transform. Proofread headings.

What about German nouns or Irish prefixes?

Latin-script tricks mis-handle many languages. Do not ship a legal heading from this box alone.

Will this slugify a URL?

No. Use slugify so spaces become hyphens and punctuation drops.

camelCase vs PascalCase?

Use the style the form lists. We do not infer your language’s identifier rules.

Is the text uploaded?

No.
