- description
- Convert text between different case styles. Use when the user asks to convert text to camelCase, snake_case, kebab-case, PascalCase, UPPERCASE, lowercase, Title Case, CONSTANT_CASE, dot.case, path/case, Sentence case, inverse case, alternate case, or any other case format.
Case Converter
Convert text between 15 different case styles simultaneously.
Input
- The text to convert
- Optionally, the target case style (if not specified, show all 15)
Output
- The converted text in the requested case style(s)
- If no target specified, show all 15 transformations
Instructions
Apply each transformation exactly as follows:
- lowercase —
s.toLowerCase()
Example: hello world example
- UPPERCASE —
s.toUpperCase()
Example: HELLO WORLD EXAMPLE
- Title Case — Capitalize each word EXCEPT articles/prepositions when not first:
Small words (keep lowercase unless first): a, an, and, as, at, but, by, for, in, nor, of, on, or, so, the, to, up, yet, via, with Always capitalize: first word of the string, first word after ., !, ? Example: Hello World Example (but: The Art of War)
- Sentence case — Lowercase everything; capitalize first letter of each sentence (after
.,!,?followed by whitespace, and the very first character)
Example: Hello world example. Another sentence.
- camelCase — Remove non-word characters (replace with space), trim, lowercase, then uppercase the first letter of every subsequent word, remove all spaces
Example: helloWorldExample
- PascalCase — Same as camelCase but also capitalize the very first letter
Example: HelloWorldExample
- snake_case — Lowercase, remove non-word non-space characters, replace spaces with
_, collapse consecutive_
Example: hello_world_example
- kebab-case — Lowercase, remove non-word non-space characters, replace spaces with
-, collapse consecutive-
Example: hello-world-example
- CONSTANT_CASE — Uppercase, remove non-word non-space characters, replace spaces with
_, collapse consecutive_
Example: HELLO_WORLD_EXAMPLE
- dot.case — Lowercase, remove non-word non-space characters, replace spaces with
., collapse consecutive.
Example: hello.world.example
- path/case — Lowercase, remove non-word non-space characters, replace spaces with
/, collapse consecutive/
Example: hello/world/example
- iNVERSE cASE — For each character: if uppercase → lowercase, if lowercase → uppercase, else unchanged
Example: hELLO wORLD eXAMPLE
- aLtErNaTe CaSe — For each character at index i: if i is even → lowercase, if i is odd → uppercase
Example: hElLo wOrLd eXaMpLe
- esreveR — Reverse the entire string character by character
Example: elpmaxE dlroW olleH
- SpOnGeBoB cAsE — Iterate through alphabetic characters only, alternating upper/lower (non-alphabetic characters pass through unchanged, but do NOT advance the alternation counter)
Example: hElLo WoRlD eXaMpLe
Options
target— specific case name (if omitted, output all 15)batchMode— if true, apply the transformation to each line independently
Examples
Request: "Convert 'hello world' to camelCase"
Output: helloWorld
Request: "Convert 'USER_LOGIN_COUNT' to all cases"
Output:
- lowercase:
user_login_count - UPPERCASE:
USER_LOGIN_COUNT - Title Case:
User_login_count - Sentence case:
User_login_count - camelCase:
userLoginCount - PascalCase:
UserLoginCount - snake_case:
user_login_count - kebab-case:
user-login-count - CONSTANT_CASE:
USER_LOGIN_COUNT - dot.case:
user.login.count - path/case:
user/login/count - iNVERSE cASE:
user_login_count - aLtErNaTe CaSe:
uSeR_lOgIn_cOuNt - esreveR:
TNUOC_NIGOL_RESU - SpOnGeBoB cAsE:
uSeR_lOgIn_cOuNt
Request: "snake_case this: 'My Component Name'"
Output: my_component_name
Error Handling
- If input is empty, return an empty string for all cases
- If target case style is not recognized, list all 15 available styles and ask which one the user wants
- For very long inputs (>10,000 characters), process normally but note the length
