Changes the case of copied text or code, and shows the result on the row before you paste it. One action, Change case, with eleven variants:

Example

Copy parseHTTPResponse2Json, open the actions, type snake: the row shows parse_http_response2_json. ↵ pastes it.

How words are found

• camelCase and PascalCase boundaries, and acronyms: HTTPServerError is http, server, error.
• Separators: spaces, _, -, . and any punctuation. An apostrophe inside a word is dropped (don't is dont).
• Digits stay with the letters beside them (base64Encode is base64, encode), and split only before a capital (v2Beta is v2, beta).
• Emoji and CJK text are treated as part of a word and passed through unchanged.

Title Case and Sentence case keep your punctuation and spacing. They split camelCase and _ - . only when the whole line is one token (helloWorld becomes Hello World); a single leading lower-case letter stays with its word (iPhone becomes Iphone, not I Phone); in a sentence, a word like iPhone is only lower-cased and capitalized as a whole.

Casing rules (Turkish)

The Casing rules setting is Automatic (the app's language), Turkish or English. Turkish rules map i to İ and ı to I (istanbul becomes İSTANBUL, IŞIK becomes ışık); English rules do not (ISTANBUL). Title Case keeps these words small in the middle of a title: English a, an, and, as, at, but, by, for, in, nor, of, on, or, the, to, via, vs; Turkish ve, ile, veya. The rules apply to UPPERCASE, lowercase, Title Case, Sentence case and the slug. The code variants (camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, dot.case) always use English rules so identifiers stay plain ASCII-safe (getUserID becomes get_user_id, never get_user_ıd).

Slug

Lower-cases (with the chosen rules), transliterates Turkish letters and other accents (ç ğ ı İ ö ş ü, é, ß, æ, ø, ł…) and keeps only a-z and 0-9, joined by single hyphens. Text with nothing URL-safe in it (only CJK or emoji) pastes nothing and says so.

Lines

Multi-line text is converted line by line: line breaks, blank lines, and each line's leading and trailing whitespace stay as they are. In Sentence and Title case every line starts with a capital.

Permissions and tools

None. The extension only reads the item it is given and returns text; it uses no network, runs no programs and keeps nothing.

Limits

• Empty or whitespace-only text pastes nothing and says so.
• Sentence case treats a stop after a single letter as an abbreviation (e.g. this) and does not capitalize after it; other abbreviations (Dr. smith) do start a new sentence.
• English "I" is fixed in Sentence case (i think becomes I think) only under English rules.
• Long text is fine: work grows linearly and 60,000 characters take a few milliseconds, well within the hint's 500 ms.
