Helpful FAQ

When should I use title case?

Use title case for article titles, page headings, and formal labels when your style guide calls for it.

Will proper names always be correct?

No. Automated case conversion can mishandle names, acronyms, and brands, so review important text.

What is slug case used for?

Slug case is useful for URLs, filenames, tags, and identifiers that should avoid spaces and punctuation.

Text Cleanup Uses

Case conversion is useful for headlines, spreadsheet labels, imported names, code-like identifiers, and pasted text that arrived in all caps. Choose the output style based on where the text will appear: title case for headings, sentence case for paragraphs, and lowercase or uppercase only when a system requires it.

Always review proper names, acronyms, product names, and technical terms after conversion. Automatic case tools cannot always know whether API, PDF, iPhone, or a person's name should keep special capitalization.

For long documents, convert a copy first. Then scan headings, lists, and quoted text so the final version still reads naturally.
