About The Text Case Converter

This free online Text Case Converter changes pasted text into common writing and naming formats, including uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE.

The conversion runs in your browser and is useful for quick copy editing, headings, labels, variable names, filenames, slugs, and developer-friendly identifiers. For title and sentence case, review proper nouns, acronyms, and brand names after converting because automatic casing cannot always know the intended capitalization.

How to Convert Text Case

1. Paste or type your text into Input text.
2. Choose the target format from Case mode.
3. Click Convert to generate the converted text.
4. Review the result, then use Copy Output when it is ready.

Choosing Options Correctly

UPPERCASE and lowercase:
- Use uppercase for short labels, codes, and strong visual emphasis.
- Use lowercase for normalized text, tags, or simple cleanup before another conversion.

Title Case and Sentence case:
- Use title case for headings, titles, and display labels.
- Use sentence case for normal paragraphs, messages, and readable UI copy.

camelCase and PascalCase:
- Use camelCase for JavaScript-style variables and object keys.
- Use PascalCase for component names, class names, and named types.

snake_case, kebab-case, and CONSTANT_CASE:
- Use snake_case for database fields, config keys, and Python-style names.
- Use kebab-case for URL slugs, CSS-style names, and filenames.
- Use CONSTANT_CASE for constants, environment-style keys, and fixed identifiers.

Common Use Cases

• Clean up headings, labels, product names, or pasted notes.
• Convert text into variable names, route slugs, filenames, or config keys.
• Normalize inconsistent capitalization before publishing or sharing copy.
• Prepare quick test data for forms, templates, and content systems.

Quick FAQ

Does this tool store my text?
No. Case conversion is designed to run in the browser.

Why did title case change an acronym or brand name?
Automatic title case cannot know every acronym, brand style, or editorial rule. Review names manually.

What happens to spaces in camelCase, snake_case, and kebab-case?
Words are split and rejoined according to the target style, so spacing and punctuation can be normalized.

Can I convert long text?
Yes, but very large inputs may slow the browser. Work in chunks if the page becomes sluggish.
