About the Case Converter
Whether you've accidentally left Caps Lock on, need to format a title for an essay, or just want to quickly normalize some messy data, the Case Converter tool allows you to change the capitalization of huge blocks of text securely in seconds.
Available Conversions:
- Sentence case: Capitalizes only the first letter of each sentence, converting the rest to lowercase. (e.g., This is sentence case.)
- lower case: Uncapitalizes all letters. (e.g., this is lower case.)
- UPPER CASE: Capitalizes every letter in the text. (e.g., THIS IS UPPER CASE.)
- Capitalized Case: Capitalizes the first letter of absolutely every word. Useful for names or places.
- Title Case: Capitalizes the first letter of every word, except for short articles, prepositions, and conjunctions (like 'a', 'an', 'and', 'the'), unless they are the first word. Ideal for blog titles.
- aLtErNaTiNg cAsE: Alternates capitalization every single letter. Primarily used for memes.
- InVeRsE CaSe: Flips the current case. If a letter was uppercase, it becomes lowercase, and vice versa.
