About the Case Converter

Paste text and switch it between twelve cases with one tap — handy for headings, fixing accidental caps lock, and naming variables in code.

How does the Case Converter work?

Title Case capitalises the main words and keeps short words like “and”, “of” and “the” lowercase unless they start or end the title. Sentence case capitalises the first letter of each sentence.

Programming cases split words at spaces, punctuation and existing capital letters, so “Hello World”, “hello_world” and “helloWorld” all convert cleanly.

Frequently asked questions

Will it change proper nouns?

Lowercase and sentence case can’t know which words are names, so check proper nouns afterwards.
