What's the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word; Sentence case capitalises only the first word of each sentence, like normal prose.
Can I convert to camelCase or snake_case for code?
Yes — camelCase, snake_case, and kebab-case strip spaces and punctuation and rejoin the words in the format that variable names, database columns, and URL slugs use.
Can it fix text stuck in ALL CAPS?
Yes. Paste text that's shouting in caps lock and convert it to lowercase or Sentence case to get readable prose back in one click.
Will it preserve my acronyms?
Case conversion is mechanical, so an acronym like NASA becomes 'nasa' in lowercase modes and 'Nasa' in Title Case. Review the output if capitalised initialisms matter to you.
