Text Case Converter & Word Counter

Case conversions

• Title Case follows style-guide rules rather than blindly capitalising everything: minor words like a, and, of, the, to stay lower case unless they are first or last.
• Sentence case capitalises after every ., !, ? and line break.
• camelCase, snake_case and kebab-case split existing camelCase runs first, so helloWorld becomes two words. That is what makes the conversions reversible.

How the counts are made

• Characters counts code points, not UTF-16 units. An emoji or an accented letter is several units internally; counting those would report a number that does not match what you see.
• Sentences require a terminator followed by a space or the end of the text, which avoids splitting on the dots inside 3.5 or e.g.
• Paragraphs are blocks separated by a blank line, ignoring empty ones.
• Reading time uses 200 words per minute, the standard figure for silent reading of prose. Technical material runs slower.
