# Case Converter

The Case Converter changes your text to upper case, lower case, title case, sentence case, camelCase, snake_case and kebab-case all at once, with a copy button on each result. It runs in your browser, so your text stays on your device, and it handles accented and non-Latin letters.

Runs on your device

## How it works

1. Type or paste your text into the Your text box.
2. Look through the seven results: UPPER CASE, lower case, Title Case, Sentence case, camelCase, snake_case and kebab-case.
3. Press Copy beside the version you want.
4. Paste it where you need it, or edit the text and copy another case.

## Key facts

- **Cases**: Upper, lower, title, sentence, camel, snake and kebab
- **Runs**: In your browser, nothing is uploaded
- **Scripts**: Works on accented Latin, Cyrillic and Greek letters
- **Code cases**: camelCase, snake_case and kebab-case treat each line as one name
- **Cost**: Free, with no sign-up

## Common uses

- Fix a heading someone typed in all capitals.
- Turn a sentence into a snake_case variable or a kebab-case URL slug.
- Clean up a block of text pasted with random capitals.
- Rewrite a title so each word starts with a capital letter.

## Questions

### Does Title Case skip small words like 'of' and 'the'?

No. It capitalises the first letter of every word, which suits most headings but not strict style guides that keep small words lower case. Edit those by hand after copying.

### How does sentence case decide where a sentence starts?

It capitalises the first letter of the text and the first letter after a full stop, question mark, exclamation mark or line break. Names and the word I stay lower case, so check those yourself.

### What happens to numbers and punctuation in camelCase?

Numbers are kept as part of the words, and punctuation is dropped. So 'user id 2' becomes userId2 in camelCase and user_id_2 in snake_case.

### Is my text sent anywhere?

No. All conversions happen in your browser and nothing leaves your device.
