- People formatting Japanese text for forms and lists
- Worth noticing
- It preserves kanji, hiragana, emoji, and line breaks, with a 10,000-code-point input limit.
Field notes
Users can switch conversion direction and independently include katakana with corresponding punctuation, Latin letters and digits, or spaces; the input and result are shown together with separate copy controls. The page sets a 10,000-code-point limit, says kanji, hiragana, emoji, and line breaks remain unchanged, and warns that dakuten can change character counts and that CSV structure or encoding is not converted.
