Constant Case Converter

The Constant Case Converter is an online tool that transforms text into constant case format. Constant case, also known as SCREAMING_SNAKE_CASE, is a naming convention where words are separated by underscores (_) and all letters are uppercase. For example, 'Hello World' becomes 'HELLO_WORLD'.

Using the tool is straightforward. Simply start typing or paste your text into the input field, and the converter will automatically transform it into constant case in real-time. To use the converted text, click the 'Copy to clipboard' button and paste it where you need it.

Constant case is commonly used in programming for naming constants, configuration variables, or enum values in languages like C, C++, and Java. It's also used to define immutable values or global variables in many programming styles. The all-caps format makes these identifiers stand out in the code, signaling their special status.

The Constant Case Converter primarily focuses on letters and spaces. It will typically preserve numbers and convert spaces to underscores. Most special characters are usually removed or may be converted to underscores, depending on the implementation. All letters are converted to uppercase. It's always best to review the output to ensure it meets your specific needs.

Constant case uses all uppercase letters with underscores, while snake case uses lowercase with underscores, and kebab case uses lowercase with hyphens. For example, 'MY_CONSTANT_VALUE' is in constant case, 'my_variable_name' is in snake case, and 'my-kebab-string' is in kebab case. Constant case is specifically used to denote constants or unchanging values in programming.

Yes, the Constant Case Converter is completely free to use. You can convert as much text as you need to constant case without any cost or subscription.
