How to convert text to title case

Title case capitalizes the main words in a headline or title. It is useful for article titles, page headings, presentations, and document names.

When to use sentence case

Sentence case capitalizes the first letter of each sentence while leaving most other words lowercase. It is often easier to read in labels, paragraphs, and plain-language writing.

Slug, snake case, and camel case

URL slugs use lowercase words separated by hyphens. Snake case uses underscores, while camel case removes spaces and capitalizes internal words for programming names.
