Questions people ask

What rule does Title Case follow?

Every word is capitalised except short joining words such as "a", "of", "and" and "the", which stay lower case unless they begin or end the title. That matches the convention most style guides use for headlines.

What is the difference between camelCase and PascalCase?

Both join words without spaces. camelCase leaves the first letter lower case (invoiceTotal), while PascalCase capitalises it (InvoiceTotal). The first is common for variables, the second for class names.

Will it fix ALL-CAPS text I was sent?

Yes — Sentence case is the one to use. It lowers everything, then capitalises the first letter of each sentence, which turns shouted text back into something readable.

Does it handle accented characters?

Yes. Conversion uses your browser's own Unicode-aware casing rules, so accented and non-Latin letters are handled correctly rather than stripped.

Is anything I paste here sent to a server?

No. The whole tool is JavaScript running in your browser, and this site has no endpoint that accepts text. That matters when what you are pasting is a real API payload, a customer record, or a password.
