Tool overview
What is a Case Converter?
A case converter rewrites identifiers between camelCase, PascalCase, snake_case, kebab-case, and related styles used in code and APIs.
Why use this Case Converter?
Normalize names when renaming fields, generating DTOs, or aligning front-end and back-end conventions without manual edits.
Key Features
Multiple case styles, instant conversion, copy-ready output, and fully local processing.
How to Use
Follow these steps to get accurate results from the tool interface above.
- Paste a identifier, phrase, or multi-word string into the input panel.
- Select the target case from the mode tabs: camelCase, snake_case, PascalCase, or kebab-case.
- The output updates automatically—copy the converted identifier or pipe it to another tool.
- Use Swap to reverse-test whether round-tripping preserves semantic tokens.
- Clear both panels with Ctrl/Cmd+L when starting a new naming convention batch.
Identifier Case Syntax Reference
Case conversion splits on word boundaries (spaces, underscores, hyphens, and camelCase transitions). These inputs produce predictable outputs.
| Feature / Context | Valid Syntax Example | Common Pitfall / Invalid Example |
|---|---|---|
| camelCase | userAccountId | UserAccountIdcamelCase lowercases the first segment; leading capitals imply PascalCase input was not split correctly. |
| snake_case | user_account_id | user__account__idConsecutive delimiters collapse to a single underscore—clean double separators in source text first. |
| kebab-case | content-security-policy | content - security - policyInterior spaces become hyphens; leading or trailing spaces are trimmed before conversion. |
| PascalCase | HttpResponseCode | HTTPResponseCodeAcronyms may expand per segment—HTTP becomes Http unless you manually adjust acronym handling. |
