Case Converter
Convert naming cases locally with smart word splitting.
Case Converter transforms identifiers and titles between camelCase, snake_case, kebab-case, PascalCase, and Title Case in your browser. Paste any mixed-format string and copy the naming style you need for code, APIs, or content—without uploading text.
How it works
Type or paste input and choose a target case. The tool splits words on spaces, underscores, hyphens, and camelCase boundaries, normalizes casing, and joins tokens using the rules for your selected style. Results update live as you edit.
Benefits
- Five common developer and content naming conventions
- Smart word splitting for camelCase and mixed separators
- Live conversion with instant copy
- Fully local processing with no server upload
Use cases
- Rename variables when porting code between languages
- Convert REST JSON keys to TypeScript property names
- Turn marketing titles into URL or code identifiers
- Standardize database column names across services
Best practices
- Pick the case your target language or style guide expects
- Verify acronyms manually—API may become api in snake_case
- Use kebab-case for URLs and snake_case for Python constants
- Copy output into your editor rather than retyping long identifiers
Common mistakes
- Expecting acronyms like HTTP to stay fully uppercase in camelCase
- Pasting sentences with punctuation you still need literally
- Confusing PascalCase with Title Case for multi-word product names
- Forgetting that empty tokens from double separators are ignored
Privacy
Text is converted locally in your browser. ToolHub does not receive your input unless you separately enable on-device history.
Frequently asked questions
- Which naming cases are supported?
- The tool converts to camelCase, snake_case, kebab-case, PascalCase, and Title Case. Select a target style and the output updates as you type.
- How are words detected in the input?
- Words split on spaces, underscores, and hyphens. camelCase and PascalCase boundaries are detected so getUserName becomes get, User, Name.
- Does the Case Converter upload my text?
- No. Conversion runs entirely in your browser. Your strings never leave your device for this tool.
- Can I convert API field names?
- Yes. Paste JSON keys, database columns, or variable names in any supported style and copy the converted form for another language or framework.
- Is punctuation preserved?
- Punctuation and symbols act as word separators where applicable. Only alphanumeric word tokens are used to build the output case string.
- What happens with empty input?
- An empty input produces an empty output with no error. Paste or type text to see live conversion results.
