Writing styles
Sentence case capitalises only the first letter of each sentence and is the most readable choice for body text and most headings. Title Case capitalises major words and keeps short words like ‘and’, ‘of’ and ‘the’ lowercase, as in headlines and book titles. UPPERCASE is useful for short labels; long passages in capitals are hard to read.
Programming styles
camelCase (firstName) is common for JavaScript and Java variables, PascalCase (FirstName) for class and component names, snake_case (first_name) in Python and databases, kebab-case (first-name) in URLs and CSS, and CONSTANT_CASE (FIRST_NAME) for constants and environment variables. The converter splits words on spaces, punctuation and existing capital letters, so it can convert between any of these.
Quick fixes
Typed a paragraph with Caps Lock on? Click lowercase, then Sentence case. ‘Remove extra spaces’ tidies text pasted from PDFs and emails by collapsing repeated spaces and trimming line ends.
Frequently asked questions
What is title case?
Title Case capitalises the first letter of each major word, as in headlines and book titles. Short words such as ‘and’, ‘of’ and ‘the’ stay lowercase unless they start the title.
What is sentence case?
Only the first letter of each sentence is capitalised, like normal writing.
What are camelCase and snake_case?
They are naming styles used in programming: camelCase joins words and capitalises each after the first, snake_case joins them with underscores.
