What is Case Converter?
A case converter transforms the letter casing of text between common styles: UPPERCASE (all capitals), lowercase (no capitals), Title Case (the first letter of each major word capitalized), Sentence case (only the first letter of each sentence capitalized), and playful styles like aLtErNaTiNg case.
Changing case manually is tedious and mistake-prone, especially for long passages. A converter applies the rules consistently in an instant, which is handy for headlines, titles, CSV cleanup, and fixing text typed with the wrong Caps Lock state.
