How Text Case Converter works

  1. Type or paste your text into the input box.
  2. View all 8 case format outputs update simultaneously.
  3. Click the copy button next to the format you need.
  4. Paste the converted text into your code, document, or URL.
  • Convert a feature name into camelCase for a JavaScript variable and snake_case for a database column in one step.
  • Turn a blog post title into kebab-case for a URL slug.
  • Standardize inconsistent capitalization across a list of headings.
  • Convert a sentence to UPPERCASE for a banner or call-to-action.
  • Generate PascalCase names for React components or class names.

All conversion happens locally in your browser as you type. Your text is never sent to a server.

  • Word-boundary detection for converting from camelCase/snake_case input may not be perfect for all inputs.
  • Code-safe formats (snake_case, kebab-case, camelCase, PascalCase) strip characters that aren't valid in identifiers.
  • Designed for short-to-medium text like titles and identifiers, not full documents.

Text Case Converter

Text Case Converter transforms any text into eight common case formats simultaneously — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case. Each output has its own copy button for quick use.

FAQ

Frequently asked questions

What is the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter (e.g. myVariable). PascalCase starts with an uppercase letter (e.g. MyVariable). Both remove spaces and capitalize subsequent words.

Can I convert code variable names?

Yes. Paste any text and the converter strips special characters as needed for code-safe formats like snake_case and kebab-case.

What's the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of most words (common for headings: 'This Is A Title'). Sentence case capitalizes only the first letter of the sentence (standard prose: 'This is a sentence').

Does it handle text with numbers and punctuation?

Yes — for case formats like UPPERCASE, lowercase, Title Case, and Sentence case, punctuation and numbers are preserved. For code formats like snake_case and kebab-case, special characters are stripped or converted to separators.

Can I convert from camelCase back to words?

The converter works from your input as-is. If you paste camelCase text, the case-detection logic for splitting words may not perfectly reverse-engineer original word boundaries in all cases.

Why are there 8 different case formats?

Different contexts need different conventions: snake_case for Python/database fields, camelCase/PascalCase for JavaScript/Java, kebab-case for URLs and CSS classes, and Title/Sentence case for human-readable text.

Is the conversion live as I type?

Yes — all 8 outputs update instantly as you type or paste, with no button press required.
