Deepa receives column names from a business analyst as plain English phrases ("First Name", "Date Of Birth"). She converts each to snake_case ("first_name", "date_of_birth") for PostgreSQL schema creation without hand-typing every underscore.

✓ ALL CAPS → Properly cased title🌍 Marcus – Sydney | Web Designer
Marcus names CSS classes from Figma layer names which use Title Case ("Hero Section Background"). He converts them to kebab-case ("hero-section-background") for consistent CSS class naming without manually replacing every space with a hyphen.
✓ Hero Section → hero-sectionWhat Is a Text Case Converter?
A text case converter is a tool that transforms the capitalisation pattern of text from one format to another. Different writing contexts demand different case conventions — academic titles use Title Case, programming languages use camelCase or snake_case, CSS uses kebab-case, and body copy uses Sentence case.
Manually reformatting text is slow and error-prone, especially for long strings or batches of labels. A case converter applies the transformation instantly across the entire text, saving time and ensuring consistency.
