- Option to remove accents while keeping ñ in the text formats.
Technical details
Uppercase and lowercase conversions use Unicode rules with the Spanish locale. Title Case detects whether the text is in Spanish or English and capitalizes the first letter of every word except articles, prepositions and conjunctions (which are capitalized at the start and after a period or colon), respecting acronyms such as NASA and mixed forms like iPhone; Sentence case only capitalizes the first letter of each sentence. Programming formats (camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE) split words on spaces, symbols and existing case changes, so they also convert between each other; they are applied to each line separately, always remove accents and turn ñ into n. Reverse works on graphemes so it doesn't break emojis or accented letters. Remove accents strips diacritics (á, é, ü) and keeps ñ in the text formats.
