Examples
Converting a variable name
A variable named 'user full name' becomes userFullName in camelCase, UserFullName in PascalCase, user_full_name in snake_case, or user-full-name in kebab-case — all from the same input.
Fixing inconsistent casing in a list
Paste a list of product names that arrived with inconsistent capitalisation. Apply Title Case to produce consistent headings in one step, without manually editing each entry.
