## About

Reformat any text into the letter case you need: UPPERCASE, lowercase, Title Case, Sentence case, or the identifier styles used in programming — camelCase, PascalCase, snake_case, and kebab-case.

The converter understands word boundaries in plain text and in existing identifiers, so “hello world”, “helloWorld”, and “hello-world” all convert cleanly to any style.

## How to use

1. **Paste your text** — Plain sentences or existing identifiers both work.
2. **Choose a case** — Pick any of the eight styles from the dropdown.
3. **Copy the result** — The converted text appears instantly on the right.

## Examples

### Sentence to identifier

A phrase becomes a valid variable name.

Input:

```
the quick brown fox
```

Output:

```
theQuickBrownFox (camelCase)
```

## FAQ

### How are words detected?

Words are split on punctuation, spaces, hyphens, and camelCase boundaries, so mixed input like “userName_first” is handled correctly.

### Does Title Case follow style guides?

It capitalizes every word, which suits headings and slugs. It does not apply AP/Chicago small-word rules.

### What is the difference between title case and sentence case?

Title Case capitalizes the first letter of every major word. Sentence case capitalizes only the first letter of the sentence and any proper nouns. The tool does both.
