What is a Constant Case Converter?

A Constant Case Converter is a text formatting tool designed primarily for programmers and developers. It automatically transforms any string of text into “Constant Case” (often technically referred to as Screaming Snake Case or Macro Case).

In this format, all letters are capitalized, and words are separated by underscores.

How It Works

The tool takes standard text, sentence case, or other variable styles (like camelCase) and:

  1. Capitalizes every single letter.
  2. Replaces spaces, hyphens, or existing separators with underscores (_).
