What Case Converter cleans up
The converter rewrites your text's letter casing per rule: everything up, everything down, first-letter-of-each-word (Title Case), or first-letter-of-each-sentence (Sentence case). The words don't change; the case does.
Why small text fixes matter
The classic accident: a paragraph typed with caps lock on. Retyping is tedious and introduces new errors; pasting into this tool and clicking 'Sentence case' fixes it in two seconds with the text otherwise untouched. The subtler uses are editorial - making heading capitalization consistent across a document, or normalizing user-submitted data that arrives in every case imaginable.
How the text is handled
Paste text, click a case button, copy the result. One honest caveat: automatic conversion can't know that 'iPhone', 'NASA' or 'McDonald' have intentional internal capitals - after converting, glance over brand names, acronyms, and proper nouns.
