Microsoft Word and Google Docs both have case conversion features, but they require navigating menus and can be cumbersome for quick conversions. In Word, you need to select text, go to Format → Change Case (or use Shift+F3). In Google Docs, it's Format → Text → Capitalization.
ListWrangler makes case conversion faster for one-off tasks. Paste your text, click to convert, copy the result. It's especially useful when you're working with text from various sources - emails, web pages, PDFs, or other documents - without needing to open a full word processor.
For Title Case, ListWrangler also handles edge cases that simple converters miss. It properly handles small words like "the," "and," "of" that shouldn't be capitalized mid-title (though this depends on style guide preferences - AP style differs from Chicago style, for example).
Simply paste your UPPERCASE text into the editor above, then click the 'Transform' menu and select 'lowercase'. Your entire text will be converted to lowercase letters instantly. You can also select specific text to convert only that portion.
Title Case Capitalizes The First Letter Of Every Word, like you see in book titles and headlines. Sentence case only capitalizes the first letter of the first word (and proper nouns), like a normal sentence. Use title case for headings and sentence case for regular text.
