Case Converter
TextConvert between camelCase, snake_case, kebab-case and more
Feed in a variable name or a whole list of them, one per line, and get camelCase, snake_case, kebab-case, PascalCase, and CONSTANT_CASE back at once, genuinely useful when porting code between languages with different conventions, like moving a JS camelCase API surface to Python's snake_case. Word boundaries are detected from existing delimiters (spaces, hyphens, underscores) and from capitalization changes, so `getUserID` and `get-user-id` both convert predictably, but consecutive capitals in acronyms are inherently ambiguous (is `HTTPServer` meant to split as `http-server` or `h-t-t-p-server`?), so that output is worth a manual check. Batch conversion (multiple lines at once) makes it practical for renaming a whole set of API fields or config keys in one pass, and everything runs locally.
How to use Case Converter
- 1.Paste a variable name or string and instantly convert it between camelCase, snake_case, kebab-case, PascalCase, and CONSTANT_CASE.
- 2.Use it when porting code between languages with different naming conventions (e.g. JS camelCase to Python snake_case).
- 3.Convert a list of strings at once (one per line) when renaming a batch of API fields or config keys to match a new convention.
