CONSTANT_CASE Converter for Developers

Convert any string into CONSTANT_CASE instantly. Perfect for defining global variables, ENUMs, and configuration keys in JavaScript, Python, and C++.

Standardizing Developer Constants

In programming, global constants and environment variables are traditionally written in uppercase letters separated by underscores (e.g., MAX_TIMEOUT_RETRY). Manually converting camelCase or standard sentences into this format is tedious. This tool uses regex to parse word boundaries and automatically formats your text into valid CONSTANT_CASE.

Why Use Our Constant Case Converter?

  • Language Agnostic: Generates valid constants for almost all programming languages.
  • Smart Parsing: Correctly splits existing camelCase (e.g., 'maxRetry' -> 'MAX_RETRY').
  • Strips Symbols: Removes unsafe punctuation characters automatically.
  • Private: Your proprietary variable names are never logged or uploaded.

2.

Click 'Convert to Constant Case'.

3.

Frequently Asked Questions

How does it handle existing punctuation?

All non-alphanumeric characters (like dashes, commas, and periods) are stripped out and replaced with a single underscore to ensure a valid variable name.

Does it work on bulk lists?

Yes, if you paste a list of variables separated by line breaks, it will convert each line individually.
