Case Converter

Type or paste an identifier or a phrase below — every common case style updates live. Runs entirely in your browser, nothing is ever uploaded.

ℹ️ How this works

Words are detected by splitting on spaces, _, -, ., /, and by the boundary between lowercase/digits and an uppercase letter (so myVariableName and HTTPServerError both split correctly).
UPPERCASE, lowercase, and Sentence case work on the raw text as typed rather than the word-split version, so ordinary sentences stay intact.
Every field is read-only and has its own Copy button — click a field's Copy to grab just that version.
Runs entirely client-side on this page — nothing you type here is ever sent anywhere. The JSON API below is a separate, opt-in endpoint for scripts.

Get every case style at once:

curl -sS "https://devops.majbase.com/case-converter/api?text=myVariableName"

Returns JSON: {"input": "myVariableName", "results": {"camel": "myVariableName", "pascal": "MyVariableName", "snake": "my_variable_name", "kebab": "my-variable-name", "constant": "MY_VARIABLE_NAME", "train": "My-Variable-Name", "dot": "my.variable.name", "path": "my/variable/name", "title": "My Variable Name", "sentence": "...", "upper": "...", "lower": "..."}}

Or just one style:

curl -sS "https://devops.majbase.com/case-converter/api?text=myVariableName&format=snake"

Returns {"input": "myVariableName", "format": "snake", "result": "my_variable_name"}. POST with a JSON body {"text": "...", "format": "..."} works the same way.
