# Case Converter

Convert text between different cases instantly. Supports uppercase, lowercase, title case, camelCase, snake_case, and more.

**Use this tool:** [Case Converter](https://findutils.com/text/case-converter/)

## Programmatic access

- REST id `case-convert`: POST https://api.findutils.com/api/tools/case-convert/execute (reference: https://findutils.com/api/case-convert/)
- MCP tool `case_convert` on https://mcp.findutils.com (reference: https://findutils.com/mcp/case-convert/)

## Why use a Case Converter?

Different programming languages and style guides require different naming conventions. camelCase is common in JavaScript, snake_case in Python, and CONSTANT_CASE for constants. This tool helps you quickly convert between formats without manually retyping.

## Tips for Better Case Conversion

- When converting to camelCase or PascalCase, the tool treats spaces, hyphens, and underscores as word separators.
- Acronyms like 'HTML' or 'API' may be lowercased during conversion. Review the output and adjust if your style guide preserves acronym casing.
- Use CONSTANT_CASE for environment variables and configuration constants across most programming languages.
- kebab-case is the standard for CSS class names and URL slugs -- prefer it over snake_case in front-end code.
- Combine this tool with the Word Counter to verify your text length after conversion, especially for headlines with character limits.

## Frequently Asked Questions

### What case conversions are available?

We support UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and dot.case. That covers the most common programming naming conventions and writing styles.

### What is camelCase vs PascalCase?

camelCase starts with lowercase and capitalizes subsequent words (myVariableName). PascalCase capitalizes all words including the first (MyClassName). Both are commonly used in programming.

### How do I convert to snake_case?

Simply paste your text and click the snake_case button. The tool converts spaces and mixed case text to lowercase words separated by underscores (like_this_example).

### Can I convert multiple paragraphs at once?

Yes! Paste any amount of text and the conversion will apply to all of it. Paragraph breaks and formatting are preserved in most conversion types.

### Is the conversion accurate for all languages?

Our tool works best with Latin-based alphabets. For languages with different capitalization rules or non-Latin scripts, results may vary. Special characters are preserved.

### Does the case converter require a signup?

No. It is available with no usage limits, no signup required. You can convert as much text as you need.

### Is my text safe? Does it get uploaded anywhere?

All text processing happens entirely in your browser using JavaScript. Nothing is sent to a server, so your content stays private on your device.

### What is kebab-case used for?

kebab-case (words-separated-by-hyphens) is the standard naming convention for CSS class names, HTML attributes, and URL slugs. It is also used in some command-line tools and configuration files.

### How does the tool handle acronyms and abbreviations?

Acronyms like HTML or API are treated as regular words during conversion. In camelCase output, they become 'html' or 'api'. If your style guide requires preserved acronym casing, you may need to adjust those manually after conversion.

### Can I use this for converting programming variable names?

Absolutely. This tool is designed for exactly that use case. Paste a variable name in any format and convert it to camelCase for JavaScript, snake_case for Python, PascalCase for C# classes, or CONSTANT_CASE for constants.
