What naming conventions are supported?

camelCase (myVariableName), PascalCase (MyVariableName), snake_case (my_variable_name), and kebab-case (my-variable-name) are all detected and split correctly.

What happens with acronyms like XMLParser?

Consecutive uppercase letters are treated as a single token, so "XMLParser" splits to "XML" and "Parser" rather than individual letters.

Can I convert between naming conventions, not just split?

The splitter outputs space-separated words. Use the Case Converter tool to then format those words into camelCase, PascalCase, snake_case, or kebab-case as needed.

Does it handle digits in identifiers?

Yes. Digits are treated as word boundaries when adjacent to letters (e.g., "address2Home" splits to "address 2 Home"), matching how most naming style guides treat numbers.

CamelCase & snake_case Splitter

Splits programming identifiers (camelCase, PascalCase, snake_case, kebab-case) into their component words. Useful for converting variable names into readable text, generating documentation, renaming identifiers, or simply understanding unfamiliar code. Supports all four major naming conventions.

Runs entirely in your browser — your input is never uploaded, stored, or logged.

Paste identifiers and get their words separated — process entire files of names at once. After splitting, use the Case Converter to convert the words into any other naming convention.
