Case Converter vs. Word Processor Functions

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).

FAQ

Frequently Asked Questions

How do I convert uppercase to lowercase?

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.

What is title case vs sentence case?

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.

Will it preserve my formatting?

Yes, case conversion only changes the capitalization of letters. All other formatting like line breaks, spaces, numbers, and punctuation remain exactly as they are. Your text structure stays intact.

Can I convert only selected text?

Yes! Select the specific portion of text you want to convert, then use the Transform menu. Only the selected text will be changed, leaving the rest of your document untouched.

Does it work with non-English characters?

Yes, ListWrangler handles accented characters (like é, ñ, ü) and characters from many languages correctly. The case conversion follows Unicode standards, so characters like É properly convert to é and vice versa.

What is alternating case used for?

AlTeRnAtInG cAsE (also called spongemock case) alternates between uppercase and lowercase for each letter. It's primarily used for humor or sarcasm on social media, mimicking the 'Mocking SpongeBob' meme format.
