Frequently Asked Questions

What's the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of each word, while Sentence case only capitalizes the first letter of each sentence. Title Case is used for headings, Sentence case for regular text.

What is the catalytic converter?

A catalytic converter is a device in a vehicle's exhaust system that converts harmful pollutants into less harmful emissions. It is different from a text case converter, which is a software tool used to change the capitalization format of text between uppercase, lowercase, title case, and other formats.

How to change caps to lowercase in Word?

In Microsoft Word, select the text you want to change, then press Shift+F3 to cycle through uppercase, lowercase, and title case. You can also go to the Home tab, click the Change Case button (Aa), and choose from options like lowercase, UPPERCASE, Sentence case, or Title Case. Alternatively, paste your text into an online case converter tool like utilAZ for instant conversion.

Should it be capitalized in a title?

In title case, major words like nouns, verbs, adjectives, and adverbs are capitalized, while minor words like "in", "the", "a", "an", "and", "or", and "but" are typically lowercase unless they are the first or last word. Different style guides (APA, Chicago, MLA) have slightly different rules, so check the specific guidelines for your context.
