Frequently Asked Questions
- What gets inverted?
- Only letters (A–Z, a–z). Uppercase becomes lowercase and lowercase becomes uppercase. Numbers, spaces, and punctuation stay the same.
- Same as toggle?
- Yes. Invert case and swap case mean the same: flip each letter's case. It's not title case or sentence case—every letter is reversed.
- Use cases?
- Fixing accidentally caps-locked text, creating emphasis (e.g. sArCaSm), or normalizing mixed-case data.
