Practical usage guide
What this tool does
Text Case Converter turns detected words into camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, title case, sentence case, lowercase, or uppercase. Identifier modes are useful when moving labels between code, documentation, environment variables, and URLs.
Word detection is heuristic. Acronyms, digits, punctuation, and existing camelCase boundaries can be interpreted differently from a language-aware editor, so review names that form public APIs or permanent identifiers.
Quick start
Paste a label or identifier
Use spaces, punctuation, underscores, hyphens, or existing case changes to indicate word boundaries.
Choose the destination convention
Use camel or Pascal for code, snake or constant for data and environment variables, and kebab for many URL or CSS conventions.
Review acronyms and numbers
Check names such as OAuth2Client, APIResponse, and version labels because automatic capitalization may not match a project style guide.
Common use cases
Create code identifiers
Convert a product label into variable, class, constant, or file-name conventions.
Map field naming styles
Preview how API fields might look when translating between snake_case and camelCase conventions.
Normalize headings and labels
Apply consistent title, sentence, lower, or upper case to short interface copy.
Limitations and important notes
Identifier modes primarily detect ASCII words
Pure Chinese text may produce an empty result in camel, Pascal, snake, kebab, or constant modes. Lowercase and uppercase preserve non-Latin text.
Title case is not language-aware
The tool does not apply editorial rules for articles, prepositions, names, or locale-specific capitalization.
Identifier conversion removes punctuation
Symbols are treated as separators in identifier-style output. Keep a copy of the original when punctuation carries meaning.
